I am working on setting up a new tank, I have a few questions and was wondering everyones thouht. The tank has duel over flows and returns. What is the best way to plumb the tank? Should I plumb both sides into their own sump? I think I can fit 2 30 gallon sumps in ther stand.is this over kill? The store I got the tank from recommended a single 30 gallon sump that has a spot in the middle for a protein skimmer the refuge was on on side and the returm was on the other. The guy told me that I would need to have the overflow drain into both the skimmer and return, then pump the water over to the refuge. Does this sound right?
