emerald mythrax crabs eat some kinds of bubble algae.Blue legged hermits seem to do a better job when the algae is very short.They can irritate corals and cause them to close up by climbing on them.They may also pull food out of corals when you feed.

Its a very good article but really doesnt give a sure way of killing either Algae..

if the rock is isolated to a couple pieces i would pull them out and put the rocks in darkness for about 3 months. if you pull the hair algae, it just spreads in the tank.
