The Rock was supposedly cured Rock that was actually given to me in 2 really cool boxes as far as boxes go. The inside of them was like a little styrofoam cooler she said that they were the boxes that they received the Fish in. Since they boxes on the outside had tickets from Good ole Pittsburgh International I tend to belive her.
Ok, now I see what is going on. That is basically the same thing you can get online. It is sold online as "Pre-cured" LR
, for lack of a better term. It has to go through a curing process again since it has been out of the water for a while and the life has started dying on it. For example, the rock you have was probably transhipping from an island (Marshal, Fiji, etc...) to the airport, and then the lady picked it up to give it to you. It has probably been out of the water for at least 3-5 days and die off occurred.
Again, this is all normal and will "re-cure" again.
