hey guys, so im debating on if i should get a circulation pump for my 55 gallon cichlid tank. i decided to post a thread on here to see what you guys think before i spend money on it. for filtration i have a fluval 406 canister filter and a marineland penguin bio wheel 200 power filter. i was thinking it would be a good idea to get the pump just so the fish waste can get off the bottom and sucked into the filters. let me know what you guys think and what size pump i should get if i need one.
