Seeing Red

[liquorfish]

My LR is starting to get a lot of red color on it. Not sure if this is coralline or some kind of algae. Have'nt noticed many reef tanks with so much if this color. Please see pic attached. Any ideas????
:notsure:

Looks like coraline, is it hard?

I used a toothbrush on it and does not come off. With the actinics on, it has a orange glow.
