Problem with corals

[Seamonkey]

I had the unfortunate luck to get cyanobacteria in my reeftank once. No matter what I did, water changes, turkey basting, sucking it out, it just got worse and worse. I was ready to tear the tank down. I used a product called maracyn (eurethroymycin) and it cleared up the problem within 3 treatments. (In my tank it did not harm any of the soft corals, fish or inverts that I had) and I have never had this problem again.
NOT THAT I AM SUGGESTING YOU USE THIS, cause i'm no scientist. I just know that I was so desparate that I had to do something, even if it meant the whole tank crashed, cause in my opinion it would have anyway without intervention of some sort. For me this was a success. Don't know what other people do to fight off this invasive algae. Hope you find help, cause it sure looks like my tank did when it started.
