I had a few small pieces of Halimeda which bleached out and died, now there is green algae type stuff growing all over it, not a very good picture but it looks like tiny stems all over with little green balls on the tips

well today it looks like the cyano might be winning, I think its killed off most of this mystery algae

It is a type of caluerpa

I do have a few strands of grape caulerpa in the sump, odd it only showed up on the dead halimeda
