Based on the number of posts, I believe that you have a young tank. If they are what I think they are, the bubbles are oxygen from photosynthesis. If this is the case, they are probably not there when the lights come on in the morning and then show up. This is common with a new tank.
Nitrogen will sometimes bubble out of the sand with an established deep sand bed, but not from the rocks.

I get those bubbles coming from my sand, but I didn't think it was considered a DSB (it's around two inches deep).
