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.

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.
