A reverse osmosis (RO) unit might be an overwhelming aquarium equipment, but once you get to know its functions and its benefits, you might be considering to get one. A reverse osmosis (RO) unit comes in handy when you want to have clean, safe, pure and high-quality water for your aquarium. This article will discuss the basic things that you need to know about reverse osmosis systems and show our top picks for the best units out there.

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