Canister filters are a type of aquarium filter that uses a motor to draw water through a series of filter media, such as activated carbon, ceramic rings, and filter floss. This process removes impurities from the water, such as dirt, debris, and harmful bacteria.
Canister filters are more efficient than other types of filters, such as hang-on-back filters and power filters. They also require less maintenance, as they do not need to be cleaned as often. Canister filters are a good choice for large aquariums, as they can handle a high volume of water.
