Algae ID

[mic209]

Any idea what this is and how to get rid of it? It's only growing on a couple dry pieces of rock I added a few weeks ago. It's not a sponge as it almost disintegrates when I hit it with a baster.

Looks like Chrysocystis, aka "golden noodle algae." Someone else will have to chime in about how to control them, though - I just deal with IDs
