When the tank is running Mike, where is the water level inside the OF box? From my experience with the durso the top of the Tee where it meets the 90 should be just below the bottom of the teeth on the overflow and your water level should be about the halfway mark on the tee to 90 section. I also cut down the top of the tee as short as possible and have cut the 90 end facing down shorter as well.
