Are you running a skimmer? Maybe its comming from the skimmer

It is probably air bubble being released by algae on the rock.

thanks murfman...would you happen to know if this is a good algae or bad one?

I am wondering if its not Bubble Algae the poster is refering to...

All algae will produce oxygen. Whether it's good or bad is just a matter of how much the algae bothers you.

Here is a good source of info;

I always sweep the bubbles. I've had some turn in to bubble algae.
