Actually, not at all. I have

NEVER! Not since day one of the tank. I have incredible flow, new bulbs, I under feed my tank, exceptional filtration, there is NO way I should have cyano, yet, it grows in the darkest parts of my tank, on powerheads and in front of the returns of my closed loop. Cyano is a bacteria, not an algae. There are so many different forms and it's next to impossible to know what is feeding it sometimes.
Of course, you need to be sure you do not have excess nutrients. Agreed. But I got Cyano after trying bio pellets and I can't get rid of it, despite trying everything that has been suggested. Even Red Slime Remover. Something is feeding it. Just can't figure out what. The funny thing is, my tank, otherwise is all but perfect. Corals are happy, fish are happy, parameters are spot on and it only grows on the rocks, never the sand. Go figure.
