My Tank Thread
I will be getting a 180g tank that will have a synergy shadow external overflow. The 3 drain pipes are 1.5 inches. I will be running a basement sump and need to get the pipe size down to be able to fit all 3 between the floor joists. What is the smallest I can reduce them down to? 2 returns are 3/4 inch with a vertical lift (head pressure) 8-9 ft.
