So i'm starting to plumb the tank i have a reg 30 gallon to use as a sump the only problem i'm facing is how much gph to use for the over flow, and do you need to put one on each end of the tank to even the flow, if that's the case would two 300 gph's be enough to be drained into the sump, with protein skimmer etc then be pumped back out with 450 gph or so pump.
