Do you have airline tubing or a hole in the top of your durso?
If you do, you need to adjust how much air is going into the tubing. I used an adjustable clamp to crimp the airline tubing on my overflow. The way mine works is that if the tubing is totally crimped, the overflow sucks at full gph, but if i open it a little, i can adjust how fast it drains. You just need to find a sweet spot between your return pump and the suction of your durso tubing.
