Help with micro bubbles please

I have a ton of micro bubbles and can't figure out where they are coming from. I'm not currently running a skimmer. I have a return pump, power head and water is where it should be. I'm lost here.

It looks like there's an airline going to one of the pumps, if so that might be the source. If the valve is closed you might try pinching the line close to see if that stops them. It's rare but plumbing and Loc-Line can develop tiny leaks where air is sucked in like in a venturi so you might try redoing the joints in the return that is above the water line.

Air is getting drawn into the return line somewhere. Check all the connections and you should find the problem.
