I would look up the many many threads on dinos. My corals lived by I was not housing SPS. as @Crashjack said, it's a multi-faceted approach. He (she?) is correct, just a blackout may not do it. I had been dosing NoPox for months prior, increased Reef Roids, scrubbed and scrubbed, water changes, Chemiclean... finally black out. Was it a culmination of everything and the blackout carried me over the top? Probably... did he help me? Definitely. Dinos are a nasty business. What works for one may not work for others. There are several forms of dinos - which you can only positively identify with a microscope.
Some use UV, some don't.... some dose peroxide.... some vodka.... so many options. It will be trial and error until you finally get clear of it.
It has bubbles and hairy, after feeding the tank with RR foy worse
