What is this purple stuff

[Treenk]

So I bought a frag and it was on what looked like a purple rock. But the frag died and the purple stuff ran wild. Anyone know what it is, and what j should do?

Looks like cyano, does it blow off easily?

 

[Treenk]

Hm, I didn't even think of that. I did have cyano during first 6 months, but I haven't seen it in 5 months ill take a baster once I get the chance today. Should I move all of the other frags off of the wrack before I do it?

Cyano use chemiclean and increase flow
