Help with lots of air bubbles

[oceanlife83]

I have a 120 with dual overflows that are one inch drains. They go down into sump but create so any air bubbles that turn into micro bubbles that my baffles in sump do not get rid enough because there is so many. Anyone have any advice how to fix ? As you can see in pictures I had to throttle valves to stop some of the air bubbles.

You could put a filter sock where the drain empties in your sump
