I’m getting ready to drill a tank for the first time and am trying to plan out the return line(s). It’s a 120g (4x2x2) tank and I’ve got a 1200gph rated overflow box that I’m drilling for.
Is there a big advantage to drilling two return lines (3/4” ID) or should I keep it simpler and drill one (3/4” ID)? I only use 1 return pump on a basement sump setup.
Has anyone had any regrets on only doing 1 or overdoing it with 2? I’ve only had 75g tanks and smaller in the past and have only done 1 over the top return previously.
Thanks for the input!
