What are these bubbles...

[Rpierce]

Can anyone tell me what these bubbles are on my coral?

Thanks in advance!

I've had that happen myself before, and I posted about it on several forums. No one seems to know what causes it. I just continued my regular reef chores and they disappeared after about a week or so. I didn't lose any of them.

So my advise is to do the same, keep everything stable and they will go away.
