Do you have skimmers releasing any micro-bubbles into the tank that just happen to be collecting on those rocks due to water flow, etc?

it's difficult to see any bubbles in the pic, but I wouldnt be sure anyway...

Bio activity of some kind, you'll sometimes see similar coming up from sand.

The bubbles are dead in the middle of the pic.
An I don't have a skimmer. I moved the rocks around a little last night an the bubbles came off but more poped up
All my parameters look fine. I have started to get some algae growth on other rocks.... I don't know if that has anything at all the do with it

I've seen bubbles like that on live rock if there's some algae a' brewin. I blow the rocks with a turkey baster before doing a water change to make sure there aren't any sediments building, and since using RO/DI water, I haven't had a problem with algae and bubbles like that. I also adjusted the flow a little in my tank to make sure there weren't any dead spots where debris could accumulate in the rocks and give algae a place to grow. It could just have been air inside the rock that got disturbed when you moved them. Try a turkey baster or toothbrush (ideally not the one you use yourself ) to break the bubbles, and see if it forms again over 24-48 hours.
