The sump is 20 gal right. Did you add more water to the sump like I said to try. I think that is your problem.
Or you have the baffle to high in your sump. What is the height of your main baffle
If that is the problem then tee off the pump to go into the return line. basically you are having the the return line split into two lines on going still to the tank and the other to the sump again..
THis will slow the flow down for you.
