Caution: When wetting the product for the first time, it should be made wet with twice its volume of freshwater by adding the product to the water. Avoid adding water to the product. Avoid using marine water for the initial wetting. Adding marine water to the dry product may generate sufficient heat to boil the water. Freshwater generates much less heat and adding the product to the water allows the heat to dissipate safely.
