I found this thread to be helpful with combating it. The dark period really helps kill it. I did not even skim, just did a 20% W/C instead of 10%.

I tried that too, did 4 days of dark, seemed to work but was short lived.
My cyano started after a few acans died from some kind of disease, a couple of them I could not remove from the tank, cyano kept returning on their skeletons, and spreading, chemiclean stopped it.
