I wouldn't do that in this case, with that much algea all dying at once all the absorbed nutrients will be released back into your system...

Best bet is to do as suggested, remove and scrub rocks with a brush, mexican turbo snails, lawnmower blenny, tangs if your system is large enough. Regular water changes, gfo and things should clear up in a few weeks.

Oh one more thing. Fire the guy who was doing the maintence
