Hi Everyone, I am getting a 55 gallon very soon (within the week) and I have a few questions. In my new tank I plan to have 1 oscar fish and maybe a pleco. I know both of these fishes are very messy fish too. So my question is should I get a canister filter (Fluval 305) or two Aquaclear 70's on my tank? The canister filter will cost around $150 and the two AC will cost around $80-90, so which one do you think I should go with to keep "cleaner water?" PS. I also doing weekly 10-20% water changes. Thanks!
