Yes sir. It is good. It is called coralline algae. Spreads fast once it gets going. Just scrape where you don't want it.

It looks like coraline algae, so I would say no, if it is in fact that.

Coralline algae is a sign of a healthy tank and looks great under black light too.

I figured that's what it was. Just wanted to maje sure cuz it was growing like crazy in multiple shades of purple/velvet color and covering everything
