Aqualifter is good fix however they get plugged themselves as well. So you will need to check on that pump periodically, which is a PITA and you will get tired of it eventually.

Now assuming that your over flow is Not CPR, then please see below..

The amount of the water flow that was mentioned earlier is one of the possible causes, when you have slow flow say 300 gph there isn't enough momentum to push bubbles forward in to the "U" pipe.

Next thing you can try is to lower your "Inner Box" down as if you would want to lower the level in the display tank. By doing so you will make sure that "U" pipe is completely resting on the lip, and submerged as much as possible on both sides (front & back).
Long side in to the outer box, short side in to the inner box.
This will get more "suction" (area with less pressure, or slight vacuum) in the section of the "U" pipe in the outer box so when bubble forms it will be sucked out.

Hope this helps.
