Just purchased an Odyssea CFS500 canister filter for my 55gallon because I want to replace my noisy bio-wheel filters. I did a modification on it and consequently there is now some extra space around the media in the canister. My question is if I put a couple of the cartridges from my HOB filter into the canister could I just remove my HOB and just run my canister? I was thinking this would essentially seed my canister to the point where it could handle my bioload. I currently have 29 juvenile (.75-1.5") mbuna and 2 young BN pleco's.
