Lots of air bubbles?

Just cleaned my 6gal nano. I had some hair algae on the water output ( if that's what it's called? ) then it started to produce a crazy amount of tiny bubbles. so much I can barely see anything in the tank.

This is what it looks like.

I wasn't keeping the reservoir water level up high enough in mine, so when water flowed over the sides into the return pump sections it produced all those micro bubbles that got sucked up into the return pump and spit back out into the display tank.

Also had a loose connection on the spout/nozzle coming off the return line into the tank

Something is pulled loose or the water level isn't high enough for the HOB filter.
