Hi Guys, 5 weeks in and loving my tank (180 mini reef) 48 gl, but bright green appearing and I'm worried about it, it looks crusty and not hairy, see pics can you tell from what it may be, read some descriptions of Coralline Algae and sounds similar.
But I would love to hear from you guys in here.

Looks similar to what I'm dealing with. Does it just blow off the rocks? I can take a turkey baster and it blows right off the rocks.

I haven't tried blowing it off, but i looks like its crusted on, I have current going across it by the way and its not looking like it would peel off.
