Can anybody explain a sure fire way to maintain the perfect balance of water going in and water going out of your sump? Also, somebody make a post about how to build and calibrate your sump/refugium that is so awesome it becomes a STICKY!
I know that there are some sumpinators out there that can do this, and I'm not one of them yet.
