I have a new 180 setup. What size plumbing do I want run back to the tank? The pump has 3/4" inlet and outlet, but someone local recommended 1 1/2" for the return line? I'll use two 3/4" loclines at the tank, would rather have a lot of pressure out of two outlets, than a trickle out of four. Any suggetions?
