Wayne, have you tried throttling down your return pump? I have tons of bubbles on the intake side of my sump but most are gone before they even get to the first divider. I was having lots of micro bubbles at first getting into the display tank but after tweaking the return pump discharge they all disappeared. My set up is nothing special, just a regular durso pipe with a hole in the top and then another 1/4" hole in the pipe just above the water surface (eliminates surging) and the pipe extends about 3" into the sump water.
