If you have a hang on back diffuser drill a small hole just below the water level. This way, the suction is relieved once the level gets that low and the siphon is broken.

Well, another opinion here. You should operate your sump with a water level that allows for any tank drainage during a power outage. You might find something in here helpful:

Scott hit the nail on the head. Ensure your sump has sufficient room for the drainage from the display. To find this out you need to measure the depth of your returns and/or overflows (witch ever is deeper) into your tank. So it would be the depth times the leangth and with of your tank divided by 231. That will give you how many gallons extra capacity your sump will need to hold. Drilling small holes in lines will work provided they are routinely kept clean....
