Cyano? Help please.

[input80]

Interesting Brad, thx.
Good luck carriej, there are quite a few posts on here regarding cyano & controlling/getting rid of it. It looks like quite the year for it, although I am only 1 yr into reefing. I have read a lot where ppl say "it happens & is caused by high nutrients". Personally I truly believe mine & a friend's cyano came from corals (bought from the same tank that had cyano). Mind you, I have no definitive proof, but the timing was coincidental, about 2-3 wks afterwards. He is using tap water & I am using ro-di water. I have also now started using MB7, after cyano is gone (visibly), which I am understanding is a deterrent.
