A 20 would work actually there Brad. when you make your return back from your sum to the tank. have the return line with a small hole just above the water line to break the siphon.
and then the over flow with the stand pipe, a little lower than the water line. It's working for me.
just make sure the return lines on the tank have the holes drilled to break the siphon. You can have many return pipes on the tank as long as they have the holes drilled VERY important.
