2 overflows is a Herbie. I am gathering you will have 2 right? not 3? Yes one elbow facinng down(for siphon) and one up(for air injected overflow). Make sure you gate/ball valve the siphon overflow pipe. If you go beananimal with 3 overflows, completely different setup of pipes. only the emergency is facing up. 1 inch for the overflows is good and 3/4 for return (just use hose and have it go over the lip of the tank. 400-600gph is good as the sump shouldnt be providing the brunt of your water turnover.
