The company I'm thinking about buying my tank from says they can drill a hole for the return from the sump anywhere I want. Where is the best place to put something like this? I've read about ones that come back into the overflow but it seems having it go into the tank would be better because it would increase flow over the live rock. Any advice is appreciated, I just don't want to screw up my tank by putting the return in a bad place.
