I have a Fluval Osaka 320 setup (85 gallons) with lots of corals & fish. I've been running a canister filter, but it's time to upgrade. I saw the RS-75 at my LFS and checked the dimensions - it will fit in my cabinet (this is rare)! The cabinet dimensions are 17" deep, 14" wide, and 23" tall, but I can cut out the back of the cabinet (don't worry, it's not load bearing) to accommodate the extra inch on the RS-75. My question is, what other parts are needed to have a completely functional sump system with the RS-75? I assume I need: - an overflow box (which one?) - some sort of regulator to prevent flooding? - a protein skimmer that will work with my 23" max cabinet height - a return pump Does anyone have any suggestions? Is there a complete kit for sale? Any help would be greatly appreciated.
