How the hell do I get rid of it? It's only on 6 of the 30 or more frags I have but it drives me nutts. It's not spreading at all but it gets pretty long. I have been pulling them out to clean them but I want to put a end to it....

I haven't tested my parameters, but I doubt that's even it, cause its just a few frags, not the whole tank.... And it's the same frags that were growing it in my nano... They even grew it in my DT but my tangs made quick work of it....


Thinking about just refragging them to see what happens.. Any clues or advice on what to try.. I even tried the peroxide dip but it was a temporary fix...
