So here's my dilemma. I bought a 56 gallon tank and am looking to put 3-4 fancy goldfish in it. I've read and heard that for goldfish the recommended guideline for amount of filtration needed is tank size x10 per hour. So for my 56 gallon tank I should have a filter or filters that filter 560 gallons per hour. I would like to either do this with one filter or break up the work to two filters and get the added benefit of if one fails the other one will serve as back up while I get the problem fixed. I was looking at the Fluval FX5 External canister filter seen here: http://www.amazon.com/gp/product/B00...SIN=B000I1O2PK It is big enough for the aforementioned filtration per hour but I'm worried it might be a big too powerful for the aquarium and the current too strong. Any thoughts or opinions would be great. I'm piecing this aquarium together bit by bit months in advance. I want it to be as perfect as possible for my future companions. Thank you so much for your input.
