Ok, I just want to make sure this is right in my own head. I have an overflow box that has 800 gph flow. I plan on using a 1/2" ID tubing to the sump. My return is also 1/2" ID do I need slightly higher gph return pump or slightly lower? I'm sure it's slightly higher, but as often as I am wrong. I don't want to chance buying the wrong return pump. lol Thanks.
