They do not "cure" the live rock. They go out on their boats on Thursday or Friday and harvest all the LR from their site and it is shipped off within a couple of days of that. Their mentality is that there is no need to cure it since it just came out of the ocean. They do have large "curing" bins where they keep the rock until it is shipped. I have found minimal die off with their rock. Just be sure you pick off any sponges that look kind of iffy. AND, since you are in Tampa I am assuming that you are going to pick the rock up instead of having shipped.
