Fluval FX6 Canister Filter

A cichlid-tank workhorse. The FX6 is rated for large tanks and moves a lot of water, so it keeps up with the heavy bioload and gives the strong current African cichlids like, and its big baskets hold plenty of biological media. Keepers like that it over-filters a typical cichlid tank (over-filtering is the goal), self-primes, and just runs.

African cichlids are messy, aggressive, and usually kept heavily stocked, which piles on a huge bioload and demands serious filtration and flow. A big canister filter gives the biological media capacity and turnover a cichlid tank needs. Keepers look for a canister rated well above their tank size with lots of media room.
