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...
