Well the guy at the LFS told me the Caulerpa was a good thing. :-(. I found more Aiptasia on the the other pieces of rock I bought. The rubble was in there to help seed the tank, so nuking them would defeat the purpose. There were only 3 pieces so I took them out and tossed them. Going to have to find another way to seed my tank with coralline.

Thanks for the advice, you guys rock!
