Filtration
Because of Mbuna's ferocious digging habits and the recommended sand/crushed coral substrate under gravel filtration is not recommended. High volume hang over the back (H.O.B.), high capacity power filters or canister filters are recommended. For example, on a fifty-five gallon aquarium will be adequately filtered with the use of two four hundred gallon per hour(G.P.H.) In more advanced setups (75 gallons or more) a refugium maybe be a more effective method for filtration. These cichlids must be kept in well filtered, heavily stocked mbuna-specific aquariums. Small, high flow circulation impellers are utilized to circulate water through crevices and stir up detritus that maybe become deposited within the rock work and caves.
