air bubbles on LR

when i skrubbed my LR the other day i broke off a chunk of ?? LIving Stuff?? from the rock. So i just put it in my tank. a couple days later i can see like little red air bubbles in it. I just thought was strange?? like maybe it was dieing or something. So i should take it out right!!!! One piece has a little red calerpa algae on it too. Should i keep the one with the calerap???? And what are the things called on the rocks that look like tiny little buds, all most like a little red anemone... thats were the bubbles are.... there on a chunk of rock

 

A picture would help iit could be Majano and red bubble algae but I would'nt throw the rock out.

 

p\prob cyano do you use RO/DI water?

 

maybe dinoflagellates

 

i use distilled
