Spa Pure Granular Chlorine 2 LbsItem #: C002311-CS20B2
A chlorinating concentrate for hot tubs.
With Spa Pure Granular Chlorine there is never a need to pre-dissolve before use. Simply add to the Spa / Hot Tub water and the product will quickly treat the water without the extra steps required with some lesser brands of chlorine.
Initially the spa should be treated with 1 tsp per 500 gallons of water.
To maintain a chlorine residual between 1 ppm and 3 ppm add this product at the rate of 1/2 tsp. per 500 gallons when chlorine residual drops to 1 ppm.
When comparing dosage amounts to other brands you will find that SPA PURE GRANULAR CHLORINE for hot tubs and spas is the best value for your money.
