Purple stuff on coral skeletons and liverocks?

[OrangetheClownfish]

Can someone pls help me identify these purple stuff on my rocks? might it be coralline algae? cuz it started popping up a week or 2 after i bought a zoa colony with coralline algae on its rock.

I hope so! It might mean my tank water's good and all that apparently.

More specifically it would signify stability. You can have good water at any one time like after a big water change but if it isn’t consistently decent at least, you probably won’t see much coralline growth in the long term
