Description

Canister filters are aquarium filters that remove the water from the fish tank through an intake tube, sieve, or valve, run it through filter media in a pressurized canister, and then pump the filtered aquarium water back into the fish tank via spill way or spray bar. Canister filters are especially good for medium to large tanks, as they can filter a large volume of water efficiently. Canister filters can be configured to provide biological, chemical, and/or mechanical filtration depending on the filter brand and the needs of the aquarist.
