Is this good or bad?

I set up my refugium today and bought some caulpura(sp).This was attatched to it.I think it's aptasia,but am not sure.I would hate to kill something if it's not a bad thing.

Looks like aiptasia to me ...

Yup, I would get rid of the Caulerpa in total now. Then don't buy anymore from wherever you got it.

+1... I got screwed over when I was new to the hobby and introduced that junk to my system thinking it was a cool hitchhiker (damnit) lol. Now I'm constantly battling the stuff
