HELP! Need to identify this algae bloom before it kills all my corals.

I also just switched to AF reef salt and have somewhat the same issue except mine is alot more minor then yours. I think its just diatom / cyano kind of mix of the both. Mine is mostly on the glass / sand bed. Ive been doing small water changes twice a week trying to get the majority of it each time.

interesting... i've been battling what i can't discern between brown cyano, dinoflagellates or diatoms since starting aquaforest salt as well.
mine collects on the substrate and seems to get worse with water changes.
i'm actually currently ditching the probiotic salt for the standard reef salt in hopes that it calms this down a little.
