What Is The Reverse Osmosis Process?

Using untreated tap water for your aquarium can do harm to its inhabitants. You may not see it, but there are certain bacteria, minerals and chemicals that are present in your tap water, which risks the health of your aquarium inhabitants. It contains various contaminants and impurities such as chlorine, nitrate, phosphate, copper, and other heavy metal chemicals. These contaminants and impurities make it possible for algae to grow at a harmful and aggressive rate. To counter this, applying an efficient filtration is not a bad choice.

The reverse osmosis process in an RO system occurs when water is drawn through a semi-permeable membrane, which makes use of membranes made from Thin Film Composite (TFC) materials. That removes up to 99% of impurities from tap water and produces water that is free from contaminants. Installing a reverse osmosis system for your aquarium will purify your water directly from your water source. A 4-stage RO/DI unit with a deionization (DI) cartridge can produce top quality water.

What Are The Benefits Of Having A Reverse Osmosis System For An Aquarium?

A reverse osmosis system or reverse osmosis unit (RO) can typically have a minimum of three and a maximum of 5 stages of filtration. This ensures water that is produced after the filtration stages is safe and pure. It is capable of separating dissolved organic molecules, metal ions, and other extremely fine particles with a particle size up to 0.001 microns, from water. But that’s not all that there is to it. There are also several benefits that you can get from installing a reverse osmosis system.

  • It is cost-effective compared to buying purified water regularly from your fish store for your aquarium.
  • It prevents excessive algae growth which is caused by the presence of nitrate and phosphate.
  • It is suitable for freshwater aquariums since it maintains the pH level of plants.
  • It is ideal for saltwater aquariums which require purified water.
  • It is ideal for reef aquariums since it manages and treats nitrate levels.
  • It requires little maintenance.

The RO unit caters to both freshwater and marine aquariums. Using an RO unit in a freshwater tank will provide water without General Hardness (GH) or Carbonate Hardness (KH) which is good for plants and soft-water fish. On the other hand, using of an RO unit for reef and marine aquariums removes impurities such as phosphate, nitrate, and silicates that can affect the health of corals and the tanks inhabitants.

What Are The Things To Consider When Getting A Reverse Osmosis System?

RO units are beneficial to your aquarium. But before planning on getting a reverse osmosis system for your aquarium, there are a couple of things that we would like to point out for you to consider.

  • Pure RO water can cause drastic pH changes which can be lethal for freshwater aquarium inhabitants. You can choose the best pH meter for your fish tank here.
  • Pure RO water can cause harmful conditions for being too sterilized if not chemically altered to fit the aquarium inhabitant’s need.
  • Pure RO water must be added with the necessary minerals before it can be added to certain types of aquariums. Several ways of doing this is adding tap water, water conditioner, and other liquids that would suit your aquarium needs.

Reverse osmosis systems don’t come cheap. Choose the one that is right for your tank since most reverse osmosis systems may cost you several hundred dollars. However, the cost will be worth it once you see the improvement of your tank’s water quality.

You also have to consider the replacement of certain parts, most especially the membranes that usually suffer from wear and tear. You should also prepare to utilize the waste water since RO units produce large amounts of this. Wastewater contains all of the filtered minerals and nutrients which may be harmful for your tank inhabitants but great for watering your plants.

What Are The Components Of A Standard Reverse Osmosis Unit?

A reverse osmosis (RO) unit is comprised of several key components with different functions. Being familiar with each of them is a good step before getting one. The components of a reverse osmosis unit are the following:

  1. Membrane – The membrane is semi-permeable and strains all the impurities and contaminants from tap water, allowing only the filtered water to pass through.
  2. Flow Restrictor – This manages and allows pressure buildup in the unit.
  3. Flush Valve – The flush valve washes the deposits from the membrane.
  4. Pre-filters – This part removes the components of tap water that can cause damage to the membrane.
  5. Waste Water Outlet – Water that contains high levels of chemicals from the filtered water flows here.
  6. Product Water Outlet – Contaminant-free water with a total dissolved solids (TDS) with a level of 10ppm or below flows here.

5 Best Heaters For Your Aquarium

Is an aquarium heater important? If you have tropical or marine inhabitants in your aquarium, then the answer is yes. The aquarium heater warms up the tank’s water temperature according to what your fishes require which is usually around 78 degrees up to 82 degrees. It’s necessary to get one so that your fish will thrive healthily in your tank.

This article will help you learn more about heaters and discover some of the best aquarium heaters available.

Quick Look: Top Rated Aquarium Heaters

Fishes That Need Heaters

If you want to forego aquarium heaters, you should think twice if you have the following fishes:

Angelfish, Bala shark, Banjo Catfish, Barbs Betta fish, Black shark, Bloodfin, Cichlids, Danio, Discus, Rainbowfish, and Tetra fish.

Generally, tropical fishes cannot withstand cold temperatures as this can lead to the deterioration of their health, even premature death. Unlike non-tropical fishes which can survive even at the lowest temperature , tropical fishes are extremely sensitive to the cold.

Different Types Of Aquarium Heater

An aquarium heater is not limited to one type only. They come in different shapes and sizes. Knowing what they are and what they do can help you to choose the best aquarium heater for your tank inhabitants. There are the different types of aquarium heaters that you should probably know:

Internal Heaters

The heating element is inside the fish tank. Here are some varieties of internal heaters:

  1. Submersible - the submersible type of aquarium heater warms up the tank efficiently. It lies below your tank’s water level and must be kept submerged or else it can be damaged. It can be positioned either horizontally or vertically inside the tank. The clips and suction cup holds the heater in place. Usually, the submersible heater is placed just below the filters output.
  2. Hanging – from the name itself, this type of heater is typically hanged off the top edge of the tank, secured at the back. Its temperature controls can be accessed to the portion that is laid outside of the tank. The hanging heater must be placed below the surface of the water to prevent being damaged.
  3. Substrate – compared to the submersible and hanging heaters, this particular type is not commonly used by aquarists but ideal for planted tanks. The substrate heater, in the form of an insulated coil wire, is buried under the aquarium gravel or substrate and emits heat that warms up the water.

External Heaters:

The heating element is outside the fish tank. Here are some varieties of external heaters:

  1. In-line – before the water from the filter hits the tank, it is already warmed by an in-line heater. This particular type of external heater is attached to a section of the external plumbing that pumps water to the filter and heats it as it goes through.
  2. In-filter – there are some aquarium filters that offer the inclusion of built-in heaters. As the water passes through the filter, the built-in heater inside it also radiates heat. The water goes back to the tank clean and heated.
  3. In-sump – this type of aquarium heater can be found in the sump of a trickle filter.

These types of heaters typically have the standard parts such as the envelope which keeps the internal components from getting wet, the heating element which is a piece of resistance wire that is energized via the electric supply, and the temperature adjustment button.

Heater Installation and Use

Here are some quick tips on the installation and use of your aquarium heater:

  • Most of the internal heaters come with suction cups. Use them to place your heater on the side of your aquarium tank.
  • If your heater does not come with a temperature gauge, we suggest that you get one. This can help you in monitoring the temperature and the environment of your tank.
  • Use the thermostat to switch the heater on and off as necessary.
  • When using an internal heater, always keep the water level higher than the heater to prevent heater failure.
  • Let the aquarium water heat up first. Give it at least an hour before you start adding fishes and turn the heater on. This will prevent the glass from breaking due to temperature difference.

Choosing an Aquarium Heater

There are some guidelines that you need to know before buying an aquarium heater. When you choose a heater, choose one that is compatible or well-suited with your tank. A drop in the water temperature can be dangerous to your fish especially if you own tropical ones. To maintain the right temperature of your tank, remember that the heater size matters.

This rule should always be applied when you scout for aquarium heaters: you must have three to five watts per gallon for every 10° Fahrenheit above room temperature in order to thoroughly heat the tank and maintain that temperature. If you need more heating source, we recommend that you use several heaters instead of getting strong and large ones.

5 Top-Rated Aquarium Thermometers For Different Needs

It has been proven that aquariums are actually beneficial for our health.

Just being able to observe the marine creatures residing within an aquarium causes drop in heart rate and lower blood pressure.

Keeping an aquarium inside your home, instead of having to visit the public aquariums, can increase the benefits as you can observe your fish and plants daily.

These benefits can increase significantly if you have an aquarium inside your home, because you can observe your fish and plants daily.

But maintaining an aquarium isn’t all that easy. 

While your fish and plants provide you the relaxation you need, you also have to give them care and ensure that they are in good .

A step you might need to take is getting an aquarium thermometer.

What Are Benefits Of Having An Aquarium Thermometer?

One of the most vital things in keeping aquatic creatures is knowing the water temperature they need to survive, which has to remain , and the only way for you to observe and maintain it properly is installing a thermometer.

Some thermometers can even provide an alert feature that sets off an alarm whenever the water temperature changes from the ideal range (we’ll get to this later on).

Knowing your aquarium’s water temperature allows you to monitor your fish and plants properly. It helps you be more aware of the changes in the temperature that may affect the health of aquatic life.

Most thermometers are also inexpensive, however, this may vary depending on the types of thermometer that you want to get.

There are primarily three types of aquarium thermometers.

LCD Stick-On Thermometers

This type of thermometer comes in the form of a vertical or horizontal strip that you can stick on the outside wall of the aquarium.

The advantage of getting this type of thermometer is that they’re easy to use and are pretty much unbreakable. They can show you either Celsius or Fahrenheit readings (or both!) and you have the option of placing them on an area that will not obstruct your aquarium’s aesthetics.

One of the downsides of using this, however, is that readings can be inaccurate due to the thermometer being placed outside of the aquarium. The room temperature may also affect the thermometer, so it would be advisable to stick the strip on an area away from direct sources of heat or cold, such as sunlight and air conditioner.

It is also recommended to avoid placing the thermometer below gravel level as the reading may not be as accurate as well.

The most ideal way of using the LCD thermometer is when it’s viewed straight on, as this is how it can read temperature best. This type of thermometer can be hard to read in low light and it does not come with an alert feature.

Standing Or Floating Thermometers

This is the type of thermometer that needs to be submerged in the water.

There are various styles of floating or standing thermometers as well—there is the one that can be stuck to the inner walls of the tank using a suction cup; magnetic one that can be held by a magnet on the outside; those that are hanging by a clip; that can simply free float in the water; and , that weighted down to sink and stand on the bottom of the aquarium.

Regardless of the style of the thermometer, this type can accurately read water temperature as it is submerged. The room or air temperature has no effect on it.

There are disadvantages this type (of thermometer), however. One is the fact that it can be difficult to read—not only because it’s submerged, but also because the scale often has smaller numbers compared to other thermometers.

Another downside is that most of these thermometers are made of glass, which means it is breakable. If your fish moves around a lot, it might not be advisable to use a free floating glass thermometer.

On a good note, there are models that are made of plastic or stainless steel, which are both more durable than glass.

Similar to the stick-on thermometer, this type also does not have any alert features. However, this makes them inexpensive, which may be good if you’re on a tight budget.

While you can choose the style that you prefer, the best way to use a floating or standing thermometer is by sticking them to the inner tank using a suction cup. This way, the device will not get in the way of your fish, plants and ornaments. You also avoid the risk of infecting the water if ever the glass-type thermometer breaks.

Digital Thermometer

These thermometers come with a probe that is placed inside the tank and is connected to a digital display outside. There are models that have a cord physically connecting the probe and the display, while there are also wireless types.

Most of these thermometers are battery-operated, however, some high-end models also come with a plug that you can connect to your wall sockets or to an extension cord.

Some of the pricier models come with an alert feature that will blare an alarm when the temperature rises or falls from the desired range.

Because the probe is dipped into the water, the temperature reading is just as accurate as the floating type. It is also easy to read, similar to the LCD stick-on type, as the display is placed outside the aquarium.

The only drawback for this type is that it’s generally more expensive. Since it’s either battery-operated or plugged, continuous use also means additional expenses.

The most recommended way to use this type of thermometer is to stick the digital display on the outer tank using a suction cup, while the probe is submerged in the water. This way, you can easily view the temperature and the thermometer would not be moved around unnecessarily.

So How Do You Choose a Thermometer?

You have to weigh the pros and cons of each type against your own situation.

If the room where your aquarium is located generally does not change in temperature (e.g. no aircon or vents, thick curtains that prevent sunlight from coming in), then the LCD stick-on may be a good choice.

However, if you’re on a tight budget and your room temperature sometimes goes from warm to cool, it might be a better choice to go for a floating or standing type.

If you have the budget and you want both the accuracy and convenience, the digital type might be the perfect choice.

Another thing to consider is the type of fish residing in your aquarium. Some thermometers have a limited temperature range. For example, most floating and LCD stick-on thermometers can only read from 0 to 40 degrees Celsius.

Meanwhile, many digital thermometers are capable of reading from -50 up to +70 degrees Celsius. That’s an enormous difference, and it may or may not matter depending on what kind of fish you keep.

Additionally, if you’re a buyer who likes the assurance of having a warranty, this is another factor to think about as well. Many of the thermometers on the cheaper side do not come with warranties.

The amount of cleaning and maintenance you’re willing to do matters as well. If you would prefer not having to clean your thermometer regularly, the LCD stick-on type or the digital type may be more suitable for you.

If you don’t mind cleaning regularly, and would like to save more money, the floating thermometer may be ideal.

What’s The Best PH Meter For You: Top 5 Reviews

Being able to test hydrogen-ion activity in various products which contain water-based solutions requires accuracy, which is why finding the best pH meter is crucial. PH meters have lots of applications from checking quality control to laboratory processes.

Testing the acidity levels of food and water is probably the most vital uses of pH meters. Practically speaking, you can buy a meter for your own personal use at home or for broader uses such as in research facilities or production companies.

Though there are many products out there, they all vary in features and each has their own benefits and disadvantages. To be able to help you out, we have compiled the information you need in selecting your pH Meters as well as a list of the Top 5 Best pH Meters in 2018.

What Are Some Of The Benefits Of Using PH Meters?

No matter where you would need to use a pH meter, whether in an industrial setting or a clinical setting, knowing all the benefits would help you use them better. Who knows, you may find other uses for pH meters aside from what you already know! So read on and find out the benefits:


Rather than using old fashioned test strips or even having to carry out a titration experiment, using a pH meter to measure the acidity of a given solution is much easier. Having to determine the correct color from test strips and titrations is not really accurate since people may have different perceptions of color. With a pH meter, all you have to do is press a few buttons to control the device and it gives immediate, more precise results.

Purse And Pocket Size

The use of pH meters is truly beneficial as they are usually portable and easy to carry. No matter the meter is placed indoors or outdoors. The good thing is that it is highly portable. What better, that you don't even have to plug it into a socket when you're outdoors or in the field. It happens so as some pH meters are actually battery-operated.

User-Friendly Calibration

Most, if not all, pH meters come with calibration controls, which you will be able to calibrate yourself by following the directions in the manual. Correct calibration is essential in obtaining accurate results, especially if you are doing research or performing an experiment. Regularly calibrated and maintained pH meters will surely last for years to come and save you a lot of money!

Other Benefits also include precision and reliability, objectivity and accessibility of the product.

So What Should You Look For When Finding The Best PH Meter?

Benchtop PH Meters - Standard Vs Extended

Benchtop pH meters are very useful. These versatile versions even have the choice to add on different accessories such as printers and probe arms. The most accurate and multifaceted meters are the benchtop models.

A standard range benchtop meter covers most procedures which involve water-based solutions as it measures the standard pH scale of 0 to 14. An extended range benchtop meter, on the other hand, are used in procedures which need a base acid that falls outside the standard pH scale of 0 to 14.


  • A pH resolution of 0.001 is best for exceedingly sensitive lab applications.
  • A pH resolution of 0.01 or 0.1 can be used in standard lab applications.


When purchasing a pH meter, you must consider its durability. It should be able to withstand the elements, especially if you are to use it outdoors or in the field. It should be impervious to dirt, water and harsh chemicals, which it may come into contact with. For meters which will be used with high temperatures, check that it won't break even at a temperature of at least 71 degrees Celsius.

Automatic Temperature Compensation

Readings may be influenced by the temperature in which they are used. Consider buying a meter with an automatic temperature compensation as this additional feature is very helpful for samples which have a high temperature and no time to be cooled down before being tested.

Without this feature, you may only test samples at room temperature or make use of a temperature compensation chart in order to get the correct reading.

The Modern Touch

It would be very useful to find a meter that connects to a computer, especially when you frequently check many samples at once. Having it connect to a computer, whether using a cable or via bluetooth, will allow you to record the readings and save the important data you need.

Other Important Things To Consider

Level Of Accuracy And Consistency

Since pH meters have different uses, the levels of accuracy vary as well. For instance, measuring the acidity of different foods makes your choice of meter different as well.

You'll need a meter with an accuracy of 0.01 to 0.02 units, especially when the sugar-to-acid ratio is relevant. Incorrect readings may run the risk of permitting foods with dangerously high pH levels to reach the consumers.

For the use of meters in scientific experimentation and research, meters should be accurate within 0.002 pH units. Your pH meters should also consistently produce the same reading every time it is used. If different readings show up, then that means it is not reliable.

Ease Of Operation

Knowing how to calibrate your meter depending on your needs is essential. Accuracy can only be met when your device is correctly calibrated. Go for meters which have at least a 2-point calibration as there are 3 standard solutions for you to calibrate, pH 4, pH 7 and pH 10.

The appropriate style of electrode is also important for you to consider since it again depends on your testing needs. The ease of using your device is highly dependent on this factor. Some pH meters come with many types of electrodes, while others require you to purchase them separately.

Choose the ones with the appropriate electrodes, for example, if your solution is thick, some electrodes may get clogged, then your electrodes may get damaged and your device will be of no use.

Your Budget

Since there are many options to choose from, you have the choice to find the one that suits your budget best. Additional features may mean additional costs. Simpler meters which may cost less still have good basic features, as long as it serves the purpose you need it for.

The Reviews Of The 5 Best PH Meters

The Best Protein Skimmer For Your Aquarium

One way of successfully keeping your aquarium clean and your fishes healthy is through the use of a protein skimmer. The protein skimmer complements the aquarium filter in removing harmful waste materials by removing the excess protein in your aquarium. Protein skimming is a tried and tested process, but choosing the right protein skimmer can be a trial and error process. This article will help you in choosing the right protein skimmer

Quick Look: Top Rated Protein Skimmer For Aquariums

Purpose Of A Protein Skimmer

A protein skimmer is an type of aquarium equipment is commonly used or installed in the maintenance of a saltwater aquarium. It is specially designed to be compatible with aquariums with saltwater for the removal of proteins, dissolved organic compounds (DOC), and other harmful substances from the aquarium before being digested by the bacteria. This results in the slowing down of nitrate build-up, extension of water changes intervals, and prevention of algae build-up. Your tank will have more oxygen available to its inhabitants after the protein skimmer removes wastes before it gets consumed in the biological process.

The protein skimmer is essential and effective for a saltwater aquarium but not the same can be said if it is used in aquariums with freshwater. Fresh water doesn't have as much protein compared to saltwater which is why foam build-up isn’t that much. It doesn’t have any negative effects on freshwater fishes or your tank. The protein skimmer just won’t do much to improve the quality of the freshwater aquarium’s water.

In conclusion, protein skimmers are filters generally best suited for saltwater environments. It is important when it comes to setting up and maintaining saltwater aquariums such as the fish only setup, in which the fish only with live rock or (F.O.W.L.R.) or reef tank setups.

The Protein Skimmer And How It Works

If you are still in the guppy stage of being an aquarium owner, you might want to get a good understanding of the protein skimmer. Here are the basic things that you need to know about an aquarium protein skimmer:

  • The protein skimmer is also known as a foam fractionator.
  • A protein skimmer removes harmful organic and inorganic compounds from your aquarium before they decay and become ammonia and nitrate. It also removes dissolved organic compounds.
  • It maintains and corrects nitrate levels.
  • Protein skimmers remove waste from fish, plants, and invertebrates.
  • A typical protein skimmer is cylindrical or conical. It produces fine air bubbles that serves as an adsorbent. These air bubbles attract waste that rise to the top and then forms into foam. The foam that the waste sticks to is collected in the skimmer’s cup and removed.
  • The collected foamy waste is called “skimmate.”
  • The collection cup of the protein skimmer must be cleaned regularly.

Benefits Of Having A Protein Skimmer

As we’ve mentioned earlier, protein skimmers can be a great help in keeping your aquarium healthy and clean. However, there are still more benefits that you can get with an aquarium protein skimmer. These are:

  • It lowers the nitrate level of your tank by preventing excessive nitrate buildup.
  • It is ideal for reef aquariums since it helps lower the nitrate level which results in healthy corals.
  • It removes biological toxins from the tank.
  • It reduces aggressive algae bloom.
  • It reduces carbon dioxide buildup.
  • It improves and increases the oxygen level of your tank which is great for the health of its inhabitants.

There are plenty of benefits offered by a protein skimmer. You can still have a tank without a protein skimmer but you will have to do frequent partial water changes to avoid algae issues. This will require more effort and time on your part. A Protein skimmer can save you from all that tedious work.

Types Of Protein Skimmers

Protein skimmers come in different shapres and size, but a standard one has at least three components:

  1. The skimmer body.
  2. The air source and foam separation area.
  3. The collection cup.

Skimmers are classified according to their design and how they operate. These classifications are the following:

  1. Co-counter flow systems – air is introduced at the bottom of the skimmer body and comes in contact with the water as it rises towards the collection cup.
  2. Counter-current system – air is forced into the system under pressure and moves against the flow of the water before rising towards the collection cup. The different variations are the pin-wheel, needle-wheel, and the mesh-wheel.
  3. Venturi - a venturi valve which is situated in the intake tube is used to mix in air with the water.
  4. Needle Wheel – a spoked wheel is used which spins and chops up the incoming waterand produce fine bubbles.
  5. Spray Induction – a spray nozzle creates fine bubbles as the water is forced into it.
  6. Downdraft and Beckett – it mixes air and water to create bubbles.

The two most common types of protein skimmers are the Hang On Back (HOB) skimmer, which doesn’t take up any tank space and can be hidden behind the tank with a background, and the In Sump skimmer, which can be placed in your tank.

Best LED Lights For Reef Tank In 2019 – Top 5 Reviews

Having all the right accessories in your reef tank and setting them up is only half of the job, believe it or not. The other which is even more important is LED lighting set up. We implement it in order to amplify the beauty and attractiveness of our wonderful aquarium.

If you’re looking to enhance the looks of the aquarium, why not choose the absolute best LED lights? If you ever had a dilemma, we’re here to solve it for you and help you find the best lighting for your aquarium.

What Are Some Of The Benefits Of LED Lighting For Reef Tanks?

Adding spectacular lighting to an already amazing aquarium can make everything looks much better and captivate the attention of passers-by, friends and family. Whether it is an aquarium of biological facility or your own home, LED lights have become a staple of all aquarium sets. There’s much more to know, and it’s not all about the benefit of looks. Let’s take a look, shall we?

Safety of use

Only until recently, LED lights in reef tanks have become such an common sight. In fact, the type of lighting you were most likely to see was old-school metal halide lights or some form of weird, unnatural fluorescent lighting. The problem with these is that they were filled with metal parts and sensitive wires which could lead to fatal injuries to both the owners and the fish.

Note: what about the advantage of LED light over the old one? Why is LED much safer? Please detail them

Much Better Lighting In The Aquarium

LED lights are different from older models of illumination because they focus most of their energy on providing light, not heat. Therefore, the amount of lighting they generate is the ultimate choice for having a better reef tank.

Technology has come a long, long way and now there are many variations of LED lights for reef tanks. You can easily choose different colors, sizes, illumination intensity, and so on. There are even models which allow you to change the rhythm and intensity of the light. You can match the color of light with your sofa. So, no matter you place your aquarium anywhere; you have complete control over it.

They Produce Much Less Heat

Sometimes, having lighting in your aquarium may alter the temperature of the water and mess with the fish. This can’t be further from the truth when it comes to LED lights. What’s different with them is that they focus much of their energy solely on lighting. Did you know that neon lights and regular bulbs spend an astounding 80% of energy only on heat production, and only 20% of actual illumination?

If you opt to purchase a high-quality LED lighting system for your reef tank, you won’t face problems like this and the fish will have both enough light and the suitable temperature

Enhanced Growth Of Plants And Animals Within The Tank

Most think this is bogus, but there is scientific proof that LED lighting matches the sunlight better and allows water organisms to develop better and faster. A more natural environment means healthier fish and densely grown plants. A win-win, right?

Things To Look For And Watch Out For When Purchasing LED Lights For Your Reef Tank

Power Drainage

It’s crucial to know at which rate the LED lights expend electrical energy. Some brands don’t specify this on the product, and in such cases, you should disregard such brands. It’s important to know how much energy will be required to power the system.

Ease of installation

Some brands offer more complex and more powerful versions of LED lights for aquariums. This might lead to more complex installation processes. You should do your research online, on YouTube and inquire with the manufacturer. If you aren’t sure about whether you are capable of doing it – don’t hesitate to call up an expert!

Difficulty of use

Although operating a LED light is simple, there are some brands and models which are more elaborately designed. Think about it – do you really want to sacrifice time and hassle with access controls, just because of a little amount of light in your aquarium?


There are different grades of LED lights and you should ask yourself about how much money are you willing to spend. Most models last to about 30.000 hours give or take. A bigger investment means more hours.

Extra options

Do you want to set the changes of intensity on automatic? Do you need different colors? Do you want flickering modes on? There are all legitimate questions and they all yield extra money if you wish to purchase LED lights for your aquarium.

And Finally... Things To Consider When Buying LED Lights For Your Reef Tank

Tank Size

What are the exact measurements of your tank? You should be aware of the fact that different sizes require different lights. You wouldn’t want to overspend because of a miscalculation.

Varieties Of Plants And Animals You Have

Different kinds of plants and animals require various light intensities to be able to advance in growth and health. Make sure you inform yourself about the parameters in order to provide your fish and plants with the ultimate features to be able to grow!

Light Intensity

Some people like different colors, whereas some prefer the plain white LEDs. After you decide on which spectrum of lighting your wildlife can grow the most – it all comes down to preference!

The Budget

Make a compromise between your wishes and the money that you are able to spend. This will create the ideal choice and everyone will be happy with your new LED lights – both you and the fish!

All You Have To Know About Hob Filters And The Best Products Of 2019

A filter’s purpose is to clean. In an aquarium, it’s responsible for removing physical and soluble chemical wastes from your water.

But what is a hob filter? A new aquarium hobbyist may not be sure what it means and how it differs from other filters.

If you try to look for the dictionary definition of the word “hob”, you’ll probably find it difficult to relate the word to aquariums or even filters.

That’s because this word is not really related to it. In fact, for aquarists, “hob” is actually just an acronym standing for Hang On Back, which means a filter that is simply hanging on the back of your aquarium.

Why Should You Get A Hob Filter?

There are a lot of benefits in getting a hob filter.

Due to the fact that it’s just hanging on the back of your tank, it’s easily accessible so maintenance would not be too difficult. You can also quickly replace or remove the filter media.

Hob filters are also generally inexpensive, and provide great filtration as well. Because of the improvements in technology, most of the hob filters in today’s market make very little noise compared to their earlier versions. This makes them ideal for aquariums that are placed inside the bedroom.

What To Consider When Getting A Hob Filter

When buying equipment for an aquarium, you need to think of various things.

What type of product should you buy? Is this product better than other products?

However, they are mostly dependent on how you want your aquarium to turn out. There are no absolutely right or wrong answers for those questions, but you do have to think of them carefully. For a hob filter, these are the things you may want to consider:

1. The Flow Rate

When deciding on a hob filter, it’s important to take the size of your aquarium into consideration. If you have a big aquarium, a higher flow rate might be necessary to reduce the time needed for filtration. Similarly, a smaller aquarium or a nano reef tank may only require a hob filter with minimal capacity.

Most hob filters indicate the amount of water they are capable of filtering. There are also brands that offer the same product, but in different sizes, to accommodate various amounts of water. Some are good enough for just 5 gallons, while some can filter up to 300 gallons.

2. The Filtration Media You’d Like To Use

There are different types of filter media that you can use. While you can choose the kind of media you want, depending on the types of fish and plants living in your aquarium, many hob filters already come with their own filter media.

It’s quite common to find filters that are equipped with one or all of the three types of media: mechanical, chemical and biological. If you have a certain preference, then you should take that into consideration when choosing your hob filter.

3. Maintenance

Having to clean and maintain your filter is a given.

However, different models of hob filters may have various methods for cleaning and maintenance. For filters that have more filtration media than others, they may require a more thorough cleaning process.

Choose the type of filter that is easier to clean if you don’t have enough time for maintenance.

Most hob filters provide instructions on how to maintain the devices, so you should consider this factor before purchasing one.

These three are the most important things that are specific to the hob filter.

What Are Your Options?

It might be difficult to decide on which hob filter suits your aquarium best. To help you, we've rounded up 5 top-rated products for you to choose from. The products have a vast range of gallons per hour (GPH), as well as different filtration media to suit your preference.

What’s The Verdict?

Our top pick would have to be the AquaClear Power Filter. Not only is it available in multiple sizes, it also offers a 3-stage filtration system that involves all three different kinds of filter media: mechanical, chemical and biological.

The manufacturers also provide easy-to-follow instructions on the hob filter’s maintenance and the replacement procedure for each filter media. Not to mention, they offer a 2-year warranty.

All of these are also offered by the Fluval C Power Filter. In fact, this one even has a 5-stage filtration system, which may be more intensive compared to AquaClear’s. However, it can be quite expensive to maintain and replace all of its filter media. It’s still a pretty good choice for those who have an extra budget and prefers a more extensive filtration process.

For those who prefer an inexpensive option, or those who don’t really need a powerful high-capacity hob filter, the API SuperClean Power Filter is a great option as well.

Overall, all of these products have their individual strengths and weaknesses, so carefully measure them up to your particular needs and wants for your own aquarium.

5 Best Air Pumps For Your Aquarium And What You Need To Know

A lot of items are needed when building an aquarium.

There’s the thermometer, which helps you monitor the water temperature and ensure that it’s within the ideal range for your fish. Here is our review about best thermometer for aquarium.

Then there’s the filter, which is needed as it removes the excess food, fish wastes, and other harmful particles from the water. (Click here to read our aquarium filter reviews.)

Unlike a thermometer or a filter, however, an air pump is not considered as a basic necessity for an aquarium.

It could be necessary, but that depends on you and your fish tank.

What Do Air Pumps Do?

In general, air pumps can bring air from outside the aquarium to inside the aquarium through an outlet.

The outlet can be in form of decoration. For example, you can arrange a coral or a plant that has bubbles coming out of its center. If you enjoy having miniature structures in your tank such as a house or a ship, you can turn their chimneys into your air pump’s outlet as well.

Another option would be to use an air stone that you can hide behind plants or corals.

You can also illuminate the bubbles produced by your air pump using a colorful light source to provide more aesthetic appeal.

Aside from using the air pump to form bubbles for aesthetic design, however, you can also use it to provide more oxygen to your water. The more your water moves, the more contact it has with air, so more oxygen will then get into the water.

Providing oxygen to your tank is also the job of the filter outlet, which is why the air pump is not considered as a necessity. However, it doesn’t really hurt to have an additional back up, in case your filter breaks.

The addition of an air pump is not harmful to your fish. So if you like having an additional source of oxygen or just the nice effect of the bubbles, you can definitely get one.

There are also some types of filters that require the use of an air pump. An example would be an undergravel filter or a corner filter. However, for some of these types of filter, a water pump can also be used.

If you use protein skimmers, an air pump would be necessary as well, especially if the skimmers use air stones to produce the foam that removes organic waste from your tank.

Accessories For An Air Pump

While most air pumps come with instructions on how to install the device and its accessories, knowing the purpose of them can be extremely helpful and may give you that extra preparation you need.

There are only a few accessories that you can use with an air pump.

1. Airline Tubes

These are the tubes that you will use to connect your air pump from outside the aquarium to the ornaments or air stones inside the water.

2. Connectors or T-Valves

These items allow you to customize the air flow through multiple airline tubes. It is especially necessary if you want to connect the air pump to multiple ornaments or air stones.

3. Check or Return Valve

A check valve or return valve is a must for every type of air pump. It’s a device that allows air to pass in only one direction and prevents air or water from going backwards into the pump outlets. This can be useful whenever there are power outages or when the pump loses its power source, whether it’s the electricity or battery.

4. Gang Valve

These are used when you need more airlines than the amount supplied by the pump. It is also useful when you want to connect the air pump to various ornaments or air stones. When using gang valves, you can adjust the air flow individually to achieve your desired bubble effect from each air stone or ornament.

Before getting an air pump, be aware of what accessories you might need. This mostly depends on what you intend to use the air pump for.

Some of the most powerful air pumps are capable of pumping air to more than one tanks. If you’d like to do this as well, then the amount of accessories needed to accommodate multiple tanks would have to be well thought of.

You can check if the air pump comes with these accessories before purchasing. If not, or if the amount of accessories is not enough for what you need, you can buy them separately. Most of them are inexpensive and are fairly easy to find.

Some accessories are also offered to be bought together with the air pump as a bundle, so you can opt for those if you want to save more money.

How To Choose The Right Air Pump

This depends on what you intend to use the air pump for.

Some air pumps are suited for different sizes of tanks, but the sizes are only relevant if you intend to use the air pump to operate an undergravel filter.

If you’re using the air pump for decorative purposes, then the more ornaments you run using the air pump, the larger it has to be. Similarly, if you’re only running a few ornaments, then a smaller air pump would do the trick.

You should also consider air resistance. If you are using decorations in your tank that resist the air coming from the pump, then you might need a larger air pump. Note that larger air stones may also provide higher resistance compared to small air stones.

Additionally, if your tank is more than 20 inches high , you might need to get an air pump that is meant for deep water so that air can still be pushed far below the water surface.

What’s The Best Filter For Turtle Tank: Know It Here

Turtles are wonderful additions to any house and a tank can really change the atmosphere of a household. Aside from all the decorations and the aesthetic improvements the turtle tank provides, it’s also a big responsibility to maintain your tank at the same time. The turtles are prone to producing a lot of waste and using up all the gallons of water. This can lead to hygienic problems that may damage the health of your turtles. The solution to that problem? A turtle tank filter, of course.

Filters for turtle tanks have come a long way in recent years and have turned into true technological works of wonder. More filtration media, more power, and more stability are all advantages that a turtle tank owner has at his disposal.

The market for filters has grown immensely and there are a lot of brands to choose from. That’s why we’ve decided to aid you in providing the best possible experience for your turtles. After our quick guide and the top 5 list, choosing a quality filter for your turtle tank will be a piece of cake. Enjoy!

What Are The Benefits Of Filters For Turtle Tanks?

First and foremost, filters are used for improving the hygienic state of the water in order to improve the health of the turtles and their quality of life. Since turtle tanks are small bodies of water, the aquatic mass doesn’t move around a lot and it can easily get stale.

That means fungus, mold and other detrimental health hazards can appear. Stale and uncirculated water also lead to a lack of friendly bacteria, which are crucial to every ecosystem.

Since turtles usually live in big bodies of water, the water mass moves and there is no need for a filter, as every bit of waste is taken far away from the turtle colony. Filters for turtle tanks provide excellent alternatives to big pools and they can do the filtering in a few different, but equally important ways.

Mechanical Filtration

It is the most basic way of filtering your turtle tank. It’s the first line of defense against health hazards. This works by separating solid waste from water, usually by employing a sponge, aquarium filter floss or polyester pillow stuffing.

Mechanical way of filtration is the least expensive way of filtering water and you should take care of it. As most of the obvious stuff that’s floating around, regular cleaning is required. Knowing that the discarding process is easy, you should throw the stuffing or the floss along with the waste that has accumulated there.

Biological Filtration

It is the second way of dealing with the problem of stale unclean water in your turtle tank. Your filter can use a sponge or floss, just like the mechanical one, but the main weapon of biological filters is the friendly bacteria that grow and flourish on the filter media. The so-called bio-media can be ceramic rings, cycling accelerators, and the Seachem Matrix formula.

The filter for your turtle tank engages the bacteria to devour turtle feces, ammonia, fungi or anything else that might stand in the way of a normal ecosystem. These kinds of turtle tank filters last years and are very reliable.

Chemical Filtration

It is also crucial to keep your turtle tank clean via a filter. Chemical filters usually employ ammonia systems or activated charcoal. Keep in mind that these filters should only aid you when the turtle tank is brand new and the friendly bacteria are not set yet. Active charcoal can also be used on its own to purge the smell from your turtle tank.

Things To Look Out For When Buying A Filter For Your Turtle Tank

Picking the good filter for your turtle tank might not be the daunting task it once was, but there are still a few things to keep in mind and a few factors that may improve the life of your beloved turtles. First and foremost, you should be aware of the different filter types as well as their flaws and advantages.

In-Tank Filters

These are not so good for the turtle tank because they are prone to jamming during the water rotation process. It functions using a pump that sucks in the water and filters it while letting it fall into the tank afterward. They are inexpensive, but also inefficient.

Decorative Filters

These are basically the same as the in-tank ones, but they don’t have the appearance of a usual filter for turtle tanks. They’re masked to look like rocks so that the turtle tank looks more natural.

Undergravel Filters

As far as turtle tanks are concerned, these are somewhat of a controversy amongst the turtle tank community. They use the gravel and the sand at the bottom of the tank as filtering media.

This filter pulls the waste down to the gravel and removes it from the water. The water is the cycled two to three times and released yet again. Despite the initial hype, we don’t recommend you to buy them because of the inefficiency and proneness to breakage.

Canister Filters

These are called the champions of the filter market by some and with full right. They employ a powerful water pump to suck in the water and expose it to numerous filtering media within the canister. Many experts say that this type of filter can help you the most, as it is the safest way to make sure your water is clean and that the turtles are healthy.

Although the filter type may determine the type of life your turtles will lead, there are a few more simple factors that may influence your choice of an ideal turtle tank filter.

What Breed Are Your Turtles?

This may be crucial as some breeds don’t respond well to chemical filtration and overly thorough measures. Also, if you have a lot of smaller turtles in your tank, a big in-tank filter may be the solution if you are on a limited budget. Both the turtles and your wallet will be happy!

How Many Turtles Are There?

The number of turtles directly influences the power of your pump. The more turtles there are, the more money you will need for purchasing a pump powerful enough to filter all that waste.

How Big Is The Tank?

The water surface is an important factor in purchasing the right filter for your turtle tank. As the water quantity increases, you will need even two filters or only one with an extremely powerful water pump.

How Much Are You Willing To Spend?

People always say the ideal product is the one which has a combination of an economic price and supreme quality. By calculating your budget, you may be able to see how much you have at your disposal and at which brand you should aim for.

That should conclude the list of info you should be aware of when buying a filter for your turtle tank. The type should determine the efficiency and the size of your tank and the turtle population should determine the power. Now that that is settled, it’s time for the final showdown, in order to see the absolute best filters for turtle tanks out there.

Aqueon Betta Falls

The betta is one of the most popular tropical fish available to the aquarist. Its popularity is due in large part to its beautiful, flowing fins and tail. Many bettas exhibit brilliant colors that are sometimes the result of selective breeding, and this coloration is another factor driving their popularity with fish keepers. Bettas are also relatively easy to keep as they can tolerate a wide range of water conditions though they will thrive in a clean and heated environment.

Caring For Bettas

The most critical factor when keeping bettas is that you cannot keep two males together in a small tank. Though some success has been reported keeping multiple male bettas in large aquariums over 30 gallons they are usually kept in smaller tanks. Males kept together will tear at each other’s fins and will usually lead to the death of one of them. Just seeing each other through glass or in a betta condo can trigger aggression and lead to extreme stress and negatively impact their health. Even keeping a pair of one male and one female betta is challenging as they can also be very aggressive with each other. Additionally it is hard to find non-betta tank mates that will not either nip at the betta’s fins or be the target of a betta’s aggression. For these reasons they are often kept singly in smaller aquariums. Displaying multiple bettas usually requires using multiple tanks.

Aqueon Betta Falls

Aqueon’s Betta Falls is a new product that attempts to get around the problems of displaying multiple bettas in one unit. It is designed to allow viewing of three bettas kept in separate, small tanks. By integrating a filtration system that serves all three tanks at the same time it eliminates the need for a complete setup for each betta you wish to keep. Its unique design makes for a striking appearance and does beautifully display your bettas. Let’s look more closely at the Betta Falls and see some of its advantages and potential disadvantages.


  • Allows you to house 3 bettas in one unit.
  • Filtration keeps water clean and reduces need for water changes.
  • Stylish design is suitable for a desktop.
  • Fish cannot see each other eliminating stress.
  • Waterfall feature can be pleasing and relaxing in itself.


  • Each tank is only a little over 1/2 gallon in size.
  • Tank is not heated.
  • Potential for fish to get into another tank leading to fights and injury.
  • Can be noisy if not filled correctly.

Aqueon Betta Falls Features And Benefits

Display Multiple Bettas

The Betta Falls is designed to house 3 bettas. This is normally not possible in a tank this size. The fish are kept separated in three small tanks that share the same water as it circulates through the tanks. Aggression possible when bettas can view each other is eliminated by the use of frosted panels that the fish cannot see through.


Many betta bowls and small tanks designed for bettas do not provide filtration. These small aquariums rely on the aquarist to make daily water changes to maintain a healthy, aquatic environment for their bettas. Using Aqueon’s QuietFlow technology, the Betta Falls constantly filters the water and circulates it between the three tanks by way of the cascading waterfall feature. The flow rate can be controlled which can be key in keeping your bettas happy and safe. Filter cartridges can be easily changed as needed. The addition of filtration is a big advantage over tanks that do not offer this feature.

Aesthetically Pleasing Design

The Betta Falls is available in white or black. Its unique design makes for a more interesting display than many of the small, plastic tanks that are available and often used to house bettas. It looks great on a desk or small table. Three units can be set up back to back to create a striking circular display of up to 9 betta fish.

Reviews Around The Internet

My research has shown some mixed reviews of the Betta Falls. Positive comments have focused on the tanks’s modern appearance and the ability to have 3 bettas in such close proximity without triggering aggression. Many users find the waterfall feature to create a pleasing and relaxing sound that increases the enjoyment of viewing their fish. Reduction of water changes made possible by the filtration system is also a compelling feature of the Betta Falls.

In some cases aquarists have reported that fish can jump downstream and enter another tank. This is not something that you want to happen and there are covers included that will minimize the potential for this mishap to occur. Reducing water flow rate from the filtration system will also help prevent this problem. The individual tank sizes are rather small and may not be the optimum size for long term betta care.


1. Penn Plax Deluxe Triple Betta Bow Aquarium Tank, 0.7-Gallon

This small tank will hold up to three bettas. It holds less water than the Betta Falls. It does not include a heater and the filter requires use of an external pump. The lighting system is battery operated.

2. AquaOne Betta Villa Trio

The Betta Villa Trio is a larger tank that holds 8.4 gallons of water. It is available with LED lighting and multi-stage filtration system. It is triple the price of the Betta Falls but affords your fish more room to move.

3. Penn-Plax World Betta Fish Condo

The Betta Condo is designed to be used within a larger aquarium. It is comprised of rectangular compartments with opaque dividers to prevent aggression. It uses the light, heat and filtration of the larger aquarium that hold the condo.


The Aqueon Betta Falls is a distinctive and relatively inexpensive way to display multiple bettas. It takes up much less room than three individual tanks and the shared filtration system is a big plus for both you and your fish. While there are potential difficulties they can be addressed by using the product carefully. If you are interested in this aquarium you can check it out here.
