Importance of Aquarium Filter

A filter plays an important role to an aquarium’s upkeep. Its purpose is to clean the water of the aquarium of toxic elements that causes harmful buildup of ammonia and nitrates which may come from different sources. Nitrates are harmless in small amounts, but if left unfiltered or unmanaged, you will be risking the health of your fishes.

Your fish or other aquarium inhabitants such as turtles constantly excrete wastes. Uneaten food, decaying organic matter, dead plants, and other external particles contribute to tank pollution and deterioration of the water quality. These toxic elements can be removed by an aquarium filter. It also provides aeration. Overall, an aquarium filter such as the canister filter provides lasting, positive, and essential benefits for your tank inhabitant’s health.

There are different types of aquarium filters available, these are the Wet/dry filter, Undergravel filter, Internal filter, Power filter, and the Canister filter. These filters employ three filtration method which are the biological filtration, mechanical filtration, and chemical filtration.

Biological filtration takes place when bacteria in the tank breaks down the dangerous ammonia and converting them to nitrites which is then converted to the less toxic nitrates. Mechanical filtration involves the physical removal of harmful and toxic materials. The other filtration method, the chemical filtration, uses a filter media such as activated carbon to remove pollutants and harmful wastes.

The Canister Filter: How It Works

The canister filter is one of the more popular types of aquarium filters. The filter media is kept inside a canister where water from your aquarium is being pushed in and out via an electric pump. This process removes the wastes, debris, and contaminants from the water.

There are different kinds of filter media that suits the specific cleaning needs of your aquarium. There are biological, mechanical, and chemical filtration available. These can then be placed inside the slots of your canister filter.
