Short answer: The best canister filter for African cichlids is the Fluval FX6 Canister Filter. A cichlid-tank workhorse. The main things to weigh are over-size it, media capacity, strong flow, and easy to service.
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.

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.
