i have been tossing around theidea of redoing my plumbing on the tank. its dual corner overflow. how i have it plumbed is a drain on each side and a return on each side. would using the return as a drain also and then running the return outside of the tank and back in through the back be acceptable or would i be looking at major headaches? so basicly i would be turning the returns into drains into the sump also adnd then having the returns run outside and over the back into the tank again. i'll draw a picture and post it as soon as I can.
