Don't know what's going on, the rocks are bubbling very slowly. They grow in size and may be numbers(can't tell). Some bubbles even have red aglae on them.

Thats cyanobacteria or diatoms. It's a nuisance algae. Are you still going through your cycle?

What are your water parameters?

Your live rock isn't bubbling, the algae is forming "sheets" and bubbles form beneath them.

Water changes, up the skimmer(wetter might be better), and just try to get a clean up crew in the tank if you haven't done so already. Also when changing water siphon as much of the algae out as you can. Eventually it will subside.

As kris mentioned that sounds like cyano to me as well. Check your water parameters, especially nitrates and phosphates. Can you post a pic to verify?

Its cyano going through photosynthesis. Oxygen is a byproduct. It gets trapped in the carpets of cyano and it slowly lifts up. Underneath the pockets of air are pockets of detritus. All that needs to be removed.

Can we get some pics of this stuff? As Pedro said, it would really help with the verification of the algae.

So sad I still did not have a camera yet. It could very well be the new rock with the coral I just picked up from Magneto. That rock does have a lot of hairy green aglae.

Oddly enough, the bubbles do not appear in the green area of his rock but only with the red/purple area of mine and the only tiny red area of his.

You have coral in this tank?
Now you've got hair algae too, thats not a good thing. I doubt that once rock would spread the algae throughout the time in no time.

BTW those red/purple areas of the rock is probably the cyano(It's not a good thing and everyones working under assumption due to lack of pics).

Do you at least know your water parameters?

Yes, I do have corals here since day one. It has been 24 days since I pick it up from a former reefer for which the whole tank is a mud pot.

I clear it up and the coral seems happy so far. I got a skimmer 2 days ago and there were some skimmate. The water has been always crystal clear the 2nd day after I put back the rocks, coral and sand into the tank.

I remember seeing this bubbling once but cannot remember what did I do. Tonight is the 2nd time I see it. Just as a reminder, the hair algae I was talking about is not in my tank before. They are on the rock that I got today. All the corals that's on the rock are swelling/opening and the mushroom is like double the size before I pick it up from Magneto. Some of my coral even open up more than before that looks like they smell food or something.

Also I have cleaned the glass this morning.

Last time (i.e. before the new stuff) water parameters were
nitrite=0
nitrate=0
ammonia = ~.25-.5
ph= 8.2 or 8.4 (4got)

will do a test soon
Now
gravity = 1.021
temp: 81.8
nitrite = 0
nitrate = 0
ammonia = 0
