Algae undergoes photosynthesis, just like plants, so whenever the lights are on, it takes in water and carbon dioxide from your fish, and it releases oxygen. So this might be what you're seeing is small bubbles of pure O2 that are being released.
In general, this won't be a problem, although you don't want to have it trapped under live rock - being exposed to oxygen/air will kill the beneficial bacteria on that part of the rock.
If what you're seeing is bubble algae like what's shown in the link above, you'll want to try and remove this from the tank. Bubble algae will get to be a nuisance, and if you break open one of the bubbles when it's in the tank, it will release spores and reproduce. I recommend removing the entire piece of live rock in a plastic bag or container before your next water change, and cut/scrape the bubbles off from the very base while the rock is in the bag/container. This way if one breaks, it's not in the tank. You can replace each piece and move on to another as long as none break. If one does, dump that water and get more from the tank. You want the rock exposed to air as little time as possible. Then you can replace any dumped water as part of the water change.
Just be certain that any bubbles are coming from the algae itself, and not from a powerhead, skimmer, or the filter - if these are your source, adjust the water level (filter), flow rate, or flow valves just enough to eliminate bubble production. The bubbles these produce don't add dissolved oxygen to the water, water movement, circulates dissolved oxygen that dissolves at the water's surface. The only piece of equipment that should produce bubbles is the skimmer, but the bubbles should remain inside the column and not be carried out the return.

Leave it, its natural.
Mkae sure you clean your tank at least every 6 mnths though.
