Cyano? Could it be?

[1snapple]

Okay, I have been battling this algae for 2 weeks now and it won't go away, I think it's cyano but not sure.
I have turned off lights for 2 days now ad its not gone, I haven't fed anything.

Sorry for the bad picture but it's on the zoas and everything.
It seems to only be on the sand but hard to say.
Any help is much appreciated.

Yeah that looks like cyano. It might from that the area has low flow or not enough. When i had this i just used a turkey baster and sucked as much up as i could and redirected some flow and its cleared up now.

Okay, thanks. I will see what I can do.
I think i got it from over feeding but now it won't go away.
