I have a problem that I hope someone can help me with, I have a 90 that has been up for 5 years as a reef now, about 1 year ago I got a gorgoian that has been doing fine but the last three or four months cyano has been growing on it, there is a little cyano on the intake on one of my powerheads but there is no cyano to be found anywhere else in my tank, the cyano on the powerhead has not spread and I continually blast the cyano off the gorgoian with a turkey baster it just comes right back I have moved it to many differant places in my tank hoping that would help it hasn't, it is so confusing to me because the cyano is not on anything else in the tank except the one powerhead and the powerhead is on the opposite side of the tank that the gorgoian is on. Any info would be appreciated.
