Thanks. Also I received a really cool piece of some dead coral, which now is kind of like
live rock I guess. Half of it is purple and a few tips are also purple, it is some kind of hard coral.
I have a large and small piece. The small has HA and bubble algae all over it, I'm going to toss it. But the large piece only had one small bubble I could see and I removed it, is it safe?
