I also beat a complete Bryopsis outbreak in my frag tank a few months back with good old fashion clean up crew..

I added 30 blue legged hermits and 7 emerald crabs (30 gallon tank). You have to pull out all the long stuff (they don't seem to touch the long patches). It will be gone in a couple weeks with enough of them.. I suppose if the treatment didn't effect anything else in the tank, that's pretty easy though!
