Picked up this Leemar 225g, but I'm kind of lost as to what approach to take with it. Previous owner had it set up as a closed loop reef tank. It has a total of 7 holes drilled into it. Two within overflow box (three if you include the return hole on the side). There are four more holes drilled in the bottom of the tank that were originally set up as returns for the closed loop. I have no idea what to do with this now because all my previous tanks I ran canisters or they already came with a wet dry. Any assistance would be greatly appreciated.
