Chlorine granules are used for the disinfection of a swimming pool and are fast-dissolving. You can use Melpool 55/G Chlorine Granules, also known as shock chlorine, in a swimming pool, spa, or hot tub.
Granules are essentially powder; this is absorbed by the water more quickly than chlorine in tablet form. This ensures that the levels in the water are quickly brought back to the right level.
