Live rock

I purchased some live rock at local fish store and it doesn't look like it's alive to me. It has no color and it looks like dry base rock. I put it in two aquariums and it was the only one to develop green nuisance algae in one of them. All of the other rocks have coralline algae on them. I attached a picture

and I would really appreciate any responses.
