Popular Sanitation Method Makes Its Way into the Hot Water Market

Several manufacturers are also offering retrofit chlorine generators that simply ‘drape over’ into the hot tub water.

Saltwater systems have become extremely popular over the past five to 10 years. The system’s popularity, however, began with pools, to improve the swimming experience while simultaneously reducing the number of traditional chemicals needed to sanitize the water. Add to this the safety benefit of eliminating the need to store large quantities of chlorine on-site. Now that salt chlorine generators … Read More
