I have a 55 gallon tank right now and I'm wondering what a good canister filter would be out of curiousity. I personally like the looks of the one with the two bio wheels for biological filtration and the cansiter for chemical and mechanical. I belive its the Magnum 350 or something. Any suggestions on a filter thats good with all three or well any suggestions. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
