Leisure Time Spa 56 Chlorine Granules are a convenient way to both sanitize and shock a spa with a powerful but gentle chlorine oxidizer. Used in small doses, it can be used as a daily chlorine treatment for indoor or outdoor spas. In higher doses, it will oxidize the water completely, to control chloramines and bromamine formation and to kill algae, bacteria and pathogenic germs in your spa and hot tub. Spa 56 also makes a great shock for bromine spas, to reactivate bromide ions. Spa 56 Chlorinating Granules are made with a soft sodium dichlor, in a 56% available formula. Spa 56 is the only spa sanitizer that is both pH neutral (7.0) and contains no calcium, so it wont add to water hardness problems. Spa 56 also contains a sunscreen, to protect it from UV degradation, which means you can.

    Chlorine tablets

    The value of it’s very expensive. I understand that the chlorine plant went down and the price went up, but it’s still very expensive.
