Unknown algae

[SuperNerd]

This stuff grows like crazy in my main tank...but see absolutely none of it in my fuge. Anyone know what it is and what will eat it? It Seems to only grow on the back wall of the tank, the glass, and on the powerheads.

It's hard to tell from a blurry picture of it dry, but it appears to be some sort of hair algae. A long spine urchin should take care of it.
