try to find out if it is indeed bryopsis, or hair algae, hair algae is a piece of cake compared to the dreaded bryopsis, hair algae you can usually add some hermits, a lawnmower blenny, or a sea hare or something, then just start doing more frequent or larger water changes, and get a better skimmer.

bryopsis, the only thing i could do (i had it pretty bad too) i pulled all the rocks out that i could remove easily, scrubbed it off with a tooth brush, and singed the roots with a small torch. rinsed the rock very very well in salt water, then put it back in the tank, had to burn it off 2 times, for everything i couldnt remove that way (bottom rocks, and sand) i would start a syphon with my gravel vac, then just pull it out easily into the syphon, if any tiny bits break off and float away, they will land in an area and resprout, so you should never just pull out what you can. i also got 3 lettuce nudibranchs to help control what was left over after all that. it seemed to work great, but i do still have a few bits here and there, mainly in my over flows.
