it's working out pretty decent actually.... I'm getting ready to set up an above tank, fuge/sump... Each side will have an overflow, the sump part will hold a skimmer, and the overflow will be designed to be a surge. It the surge fails, it will just over flow over the divider, and into the fuge, where it will drain.. I'm thinking aobut putting the two surge points, in the back top corners, pointing down w/ 45's..... We'll see how it comes out!
