Subj : filtration question To : All From : Rob McGee Date : Sun Sep 18 2005 04:17 am Hello everyone, My current tank is 55g. I got it back in the early 90s. It's been a great tank thats served me and my freshwater fish well over the years. I recently purchased an upgrade for $550. it's a used 220g tank (7' long 2' thick). it came with a magnum 350 with the bio wheels, 5 powerheads to keep the water moving, rocks, decorations, heaters, stand and canopy. really, it has everything need to get it up and running. But, I have a question or two concerning filtration. I know the amount of filtration you need depends on the amount of fish you plan on housing in the tank. but I would rather over filtrate than under :) this is what I was thinking of doing, please let me know your thoughts: Primary filtration: 2 magnum 350's w/ bio wheels. (this will give the tank a total of 4 bio wheels) Secondary filtration: 1 72"x18" Undergravel filter w/ 4 tubes and 4 powerheads. Planed fish: 1) 1 large oscar 2) 1 large clown knife 3) 2 large tinfoil barbs 4) 2 large bala sharks 5) 1 large sucker mouth cat 6) 4 med clown loach 7) 1 med firemouth Thank you for your thoughts on my planned setup and fish. BTW, currently I own the Oscar, clown knife, sucker and firemouth. ....
