I had a place nearby that got rock unlike anywhere else. This stuff was amazing, I was hoping that the stuff from fla was the same, but it wasn't as good. I would say that it is somewhere between what I got from my lfs and what you normally see in lfs (fiji rock).
The best part is that you get some colors you won't get from fiji rock. The really deep purple velvet looking stuff, some orange sponge, and some of the pink coraline algea. I had a few mullosks on the on the rocks, and a snail tagged along also.
I had a lot of die off right away. So most of the colors are gone now. But I'm starting to see some new algea growth the past two weeks. It really does spread fast. I'm having to clean the glass every other day. I'm rambling...
