Return Question for My 120 Gal Tank
I'm going to attempt to drill my aquarium. I picked up the 1500 gph kit from glass-holes.com along with a Sicce Syncra Silent 5.0 1321gph Pump (which was recommended for the kit). The return is a 3/4" set. To help with power outages I am planning to put in a 1" check valve, which should negate the back pressure of the check valve. The valve is placed at the pump, vertically as the instructions say. Do I then reduce the system to 3/4" or should I just keep the 1" and drill the tank accordingly for a 1" return. The drains via a weir setup are a dual 1 1/2" outflow.
