clear bubble goo

[weaverkb]

I'm new to saltwater and don't know what this is growing on my new rock.
I just put a rock in the tank that already had dried algae on it and now there is a clear bubble everywhere the algae was. Can anyone identify this?

If it's new rock, it could be die off. A soft toothbrush would brush it away. It also may be the beginning of a sponge. I would give it some time and find out.
