I had a cyano outbreak once really bad tht covered absolutely evrything and no flow, or cleaning, or CUC would get rid of it for me.
I bought a thing called Chemiclean Red Slime Remover and after 2 days it was ALL 100% GONE and that was without me removing most of it by hand. It literally just disappeared.
That was about 2-3 weeks ago and I haven't seen one speck of red algae since. It's 100% reef safe and safe for fish and inverts aswell. Just do a 20% waterchange after 2 days of treatment. Worked amazing IMHO.
Ofcourse now I recently have aquired a brown diatom problem, but that's another story.
