Do you have any baffels in the sump? How big is your return pump and did you plumb a ball valve on the return just after the pump.
Many times it is just a matter of too much flow through the sump, if you turn the pump down then it will probably make the bubbles go away.

helps to control the amount of flow going back to the tank.
