Product Description

  • Made from high-purity sodium dichloro granules that dissolve rapidly in warm spa water to maintain a sanitizer level of 3–5 ppm for optimal disinfection.

  • Suitable for floating dispensers or manual dosing; no need for pre-dissolving, saving time and effort.

  • UV-stabilized to maintain strength even when spa is uncovered, ensuring consistent performance.

  • Packaged in a resealable high-density polyethylene jar to maintain freshness and purity over time.
