Since the rocks are already dried. I would do an acid bath, muriatic acid, to remove a tiny layer of the surface and any po4 trapped within. Then cycle as normal, in a bin of course.

Forgot to mention the copper part.
i like the idea with muriatic or hydrochloric acid,be very careful if you are going threw with the acid treatment.Very corrosive to anything it comes in contact with.
