By the rough texture it looks like green coralline. If you rub it lightly with your finger does it rub off?

 

[Alan600]

Yeah it comes off is that good or bad ?

No worries. As long as your parameters are good your tank is fine. I used dry BRS Pukani that turned brown, then bright green (which faded in a month), now the seeded coraline is starting to grow.

Get yourself some Turbo or Trocus snails, they will mow it down.

It looks like either Green Film algae or Cyanobacteria. This doesn't always have to be that red/maroon color were all so used to.
