Hello,
I am setting up the plumbing on my rack system which has different-sized aquariums and different size pre-drilled holes. Some are drilled for a 1.5" drain and others for a 1" and 3/4" drain. My return pump is a controllable pump with a max of 3150gph. My total system volume will be about 440-480 gallons. I am shooting for something in between 2-5x turnover. Given the different-sized holes in the tanks, what size should I make the drain and the return? I know the drain has to be bigger compared to the return.
