Our chlorine shock granules (calcium hypochlorite) provide a convenient way of treating and shock dosing pools. For pools experiencing algae or clarity problems, or for any hot tub that has just been refilled. For a body of water that has turned green, or if the chlorine level is reading 0, we highly recommend using these shock granules before anything else, to kill any potential bacteria and limit any possible diseases.
