Coralline algae?

[pynakerm]

Can someone please confirm whether this is coralline algae and if so, if there anything I need to do to manage it over time? Thank you!

It is. It will spread on its own over time.

Yep. You want your rocks covered in it because a lot of algae won’t grow on top of it from what I understand

Signs of your tank maturing. Its a good thing. Be happy. Let it grow and watch your alk and calcium as consumption will increase.

This last one. It is very good to have coraline algae, but it will consume alk and calcium like coral would, so watch your parameters.
