The Best Fish Tank Filters Guide and Reviews Unlike in natural body of water where there is a constant flow of water, aquariums are stagnant and enclosed body of water. For that reason, there is a need to ensure a constant measure of maintenance to keep the water clean and healthy for plants and fishes living in it.

Contaminants of aquarium include: unfinished food particles, dead plants or animals, waste garnered from excretion and respiration of the fishes. And a very common and effective method of ridding the water of these elements is with the use of filters.

What is an Aquarium filter?

Aquarium filter is a device that removes physical and soluble chemical waste products from an aquarium. The filtration is achieved through two major ways:

Biological filtration: The excreta and decomposing components of dead plant and fishes produces ammonia which is highly toxic to the fish. The bacteria responsible for this won’t attach themselves to objects in the tank, a biological filter is like a chemically porous sponge, providing a surface for them to attach, after which it is removed and cleaned.

Mechanical filtration: It mostly involves the removal of solid waste like uneaten food, feces, plant debris etc. from the water. Mechanical filtration is attained by passing water through a sieve-like material (mesh) in other to physically trap and remove them.

Different types of filters include:

Canister filters Power filters
Algae filters Diatom filters
Baffle filters Trickle filters
Fluidized bed filter Internal filter
Airlift filters Under grave filters.

Whatever filter type you adopt may be based on factors relating to your water tank, but the basic thing to note is that filtration is an important part of keeping an aquarium clean.
