Cyano?

After being away from my tank for 5 days, I come back and see this stuff on the sand, on the glass, and in the rock. It's purple on the glass and rock and on the sand it looks either like a really dark purple or almost brown. From what I've read it looks like it is probably cyano but not sure. Is it? And if it is, should I get rid of it or will it just go away with time.

Does it come Right off if your suction it off? If so might be cyano. Maybe water flow problem.

There was some forming on the front glass but I just ran the mag float over it and it cleaned it right up. Haven't tried suctioning it.

When I look closer at it, it has a slight hairy look. Every so slightly though.

Its Cyano. Just wipe it off
