ok so here is the deal, i havent gotten my tank yet or seen its overflow, i believe that it has 2 holes in the overflow so i was thinking that i would use one to drain down to the sump and the other to have the pipe going from the sump to the tank in. that is what is in the pic. should i use both holes for a drain and put a return on one of the ends of the tank.
Renogaw, if you could find your thread for me that would be great.
thanks
