Why are bubbles coming from everything

It's not good for sponge and I wanna have it in the display area

It's becoming less then it was at one point so I'm thinking its a cycle change and a lighting change that might trigger the change. Algae and everything adjusting to the tank.

I've got that in a few spots as well and have for a while. I've got film algae on most of my rock and the spots higher up in the light produce bubbles all day. i can brush them off and they return pretty quick.

While the bubbles themselves shouldn't be an issue for most... nobody really wants all that algae. My yellow tang and tailspot might disagree tho...
