It seems that high flow prevents it, but once you got it, it feeds it.

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 have also used boyd chemi clean. It worked with no ill effects, clams and all. It was very quick too.

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.

cyano
 

i started getting it when i started using h2ocean-switched salts,a few waterchanges and chemicals-no cyano

did you use any Marko rock, Marko?(or dead/dry).....whats your feeding regiment like?.....do you rinse/strain your frozen foods (if you feed them)?

Yeah I have Marco rock that's been in there for a while, got it dry from red coral.

I feed nls daily and frozen every couple days. I've never seen any left over food

Stop feeding your tank. its worked every time anyone asked me... and regular water changes

lol and that wont cause more problems?

Ok ok that was dramatic, feed the tank much less food, dosing, and maintain parameters. its just the best advice I can give and it works :razz:
