green bubbles?

[dareiff]

Hey, I'm getting back into my 20g, after I let it set for a month with nothing in it, and now I've noticed some tiny green bubbles being "blown" on two of my three live rocks.

Any ideas? One of them has quite an outcropping, maybe 5-6 bubbles, and I just notice one on another one....
(They're dark green, and glassy)

Bubble algae (Valonia). Take them out, try not to pop them though.

It sounds like valonia, bubble algae. Are they kinda firm and can be removed whole and then popped in the air where the insides hopefully go in someone elses eyes?!! :eek2: Or look like this

haha... yes, actually, they do.
I managed to remove and loosen about 3, 2 popped, and 2 more are floating around..
Thanks
