It looks like Caribbsea might add ammonia and water to the sand to feed the bacteria alleged bacteria culture.

If ammonia is still present when it reaches the end user, it's safe to assume there is no viable nitrifying bacteria in the bag. With no nitrifying bacteria, there is no place for denitrifying bacteria to fit into the food chain.

Perhaps the include ammonium chloride to help start the cycling process for a new tank. The anaerobic conditions in the bag don't allow for nitrification, so the ammonia remains intact.
