more dumb questions

[tgoeujon]

heres the situation. i have two large rocks in my tank that i got a few months ago that have a hair algae problem. at first it was alright because my fish had it under control but now its going nuts only on those two rocks. now my question is can i put the rocks in a dark quarantine tank to get rid of the algae and if so will the few palys on it be alright in the dark long enough to get rid of the algae. or is my only option picking it all off?
