Now this doesn't look like the last stuff to me. I got this live rock from a friend that was closing his tank down. When it was in his tank there was none of these things in there. His tank had TMC LED lighting, my tank has 4 x 54 W T5's. What I can't understand is this live rock I had from him was 4 years old; how could it now start growing in my tank?
Thanks for looking
