I'm needing some feedback on what type of filteration I should install on an oceanic 58g show tank for freshwater use. I've always used power filters in the past and have had really good luck with them. The problem I'm running into is that most power filters don't fit on this type of tank. The trim on the tank is too thick to allow most power filters to fit on the back of the tank appropriately. I have been told that an Aqua Clear 500 should fit. I have also been told that the only filteration that will work is a sump or canister filter. If anyone could give their insight. I would really appreciate it!
