Brand new and more than a little confused.

Go slow, and everything will fall into place.

would it then come back real fast..and if that were to happen how could i get rid of it?

Ya, it would probably grow back in a week or two. Nutrient reduction would get rid of it, but that can be a tough balancing act in the first 6 months. And you don't want to deal with a green lawn for a reef when starting out. I'd always go new if possible until you get enough experience to tell what used rock is like.
