I am going to hook up a genx pcx30 982 gallon per hour pump on my 125 gallon tank when I set it up. What size piping should I use for the return lines? I plan on running two return lines up through the overflows and then into the tank. I know my tank isnt 180 gal plus but I figured most of you large tank guys would know this sort of thing.
