    The green one is a schlep to get rid of. Lower nutrients and phos, may just win the war. I've got some small patches only in some shaded spots.

    I've just read on RC that a good way to get rid of cyano, because it thrives off light, is to cut the lights out for 3 days straight and run actinics on the 4th day so as to not burn your corals. I was thinking about doing this so can anybody maybe verify or add to this?

    Problem with a blackout is that it only gives you a temporary fix. Its a bacteria and if some remains in the tank after the blackout it will just restart colonizing. You have to treat the cause.
