Good or bad alae?

[Bryguy]

I have never seen this kind of reddish hairy algae before and The crabs don't eat it. Is this algae good or bad has anyone had it before? And if not what should I do? It doesn't seem to be harmful but I need a second opinion.

Looks like Red Hair Algae or maybe Cotton Candy Algae to me.
