This might sound funny, maybe I'm having a brain fart. Im thinking about installing an overflow to my aquarium and installing a sump but I can't figure out how im going to adjust the return to be enough for the over flow or vice versa. I don't want to end up with a over filled sump or tank. The over flow that im going to install is 400gpm Eshopps Nano for my 30 gallon reef.
I just don't k now how to control return to overflow.
HELP!
