That is way more clear than I was. I guess the terminology is a little weird. Live Rock and Cured Rock.

As for the coralline algae thing, what about "COOKED" LR? Isn't that live? But it has no coralline on it. I have cooked LR and put it into a new tank and never experienced a cycle. Mind you, I've only been doing salt for about 3 years so I'm still new to this as well.

I hope this helps the OP. I think the most important thing is to watch your ammonia, and nitrates when you move a tank or get a new one. I have bought a few systems from Craigslist that were pretty rough looking and I used the LR from them and put them into my sump or main DT. I just watched my levels.

Good luck and let us know how things are progressing!
