So the bigger your return pump section is, the bigger water change you can do without turning the pump off, because as you start siphoning water out from the tank the water level in the return pump section is what will drop. If you prefer to turn the return pump off when doing water changes this is a moot point.

interesting.. I dont have my tank up yet so zero experience with a and overflow and sump.. I would think it would not take too much water to make the overflow stop.. I have a 120 gal and if I do a 10 % WC that is going to be 12 gallons.. seems to me that would be plenty out of the DT to stop the overflow from working.
