Spa & Hot Tub Chemicals

Hot tub water is small in volume and runs hot, so it needs regular, careful treatment. Here you'll find spa sanitizers (bromine tablets and granules, chlorine granules), spa shock, pH and alkalinity balancers, calcium hardness increaser, defoamers, clarifiers, scale and stain preventers, and cartridge filter cleaners.

Test your spa water a few times a week, keep pH between 7.2 and 7.8, and shock after heavy use. Pair these products with the right test strips and a clean replacement filter cartridge for the best results.
