Plating algae?? Sponge??

[craiguk]

So I have this growing in two places. Is pink rather than red. At first I thought sponge. But its growing flat. Almost like a thin montipora lol. Can't find a sponge or algae pic that matches. Any ideas/confirmation? Good/bad?

Coralline a good sign of stability and proper alk and cal and mag levels. Right on. Good for u.

Thanks. I thought coraline was more of a subtle colour. I'm 1 year in and only just got some coraline. not sure if that's good or bad lol
