I agree. I'm considering one now to help get some of the gear out of my tank. I was confused until I went and saw a couple at the lfs. It was a lot clearer once I was able to look at it and trace out the flow myself.

Well to answer the question of why doesn't the sump just overflow.....On my sump there are two large valves that you can open and close entirely or partially. The gph flow of the overflow with the sump valves wide open for exceeds the ~2000gph that the pumps provide. So what I do is close the valves partly until the water level in the overflow boxes is just slightly below the teeth at the top of the overflow box. What prevents the pumps from just overflowing the tank you may ask, an emergency high volume line at the top of the overflow box that leads directly down to the sump. What happens when the power goes out you may ask....well first the pumps go off... then the overflow box empties into the sump, then the tank itself back-siphons through the powerheads into the sump until the water level in the tanks drops below the powerheads. The tank is 180gallon and the sump is 40gallon. There are about 20gallons of bioballs in the sump being soaked by the returns after the water is pre-filtered with filter floss.
