Product Overview

Hot Tub Things® Chlorinating Granules are a concentrated dichlor (sodium dichloro-s-triazinetrione) sanitizer specifically formulated for hot tubs and spas. Unlike traditional chlorine tablets designed for pools, our granules dissolve quickly in warm water, providing immediate sanitization without leaving residue or affecting your spa's pH balance significantly.

This fast-acting formula eliminates bacteria, viruses, and organic contaminants, ensuring your hot tub water remains crystal clear and safe. Whether you're maintaining daily chlorine levels or shocking your spa after heavy use, our chlorinating granules deliver consistent, professional results.

  • For Daily Maintenance: Add 1/2 teaspoon per 100 gallons of water daily, or as needed to maintain 3-5 ppm free chlorine.

    For Shock Treatment: Add 1-2 tablespoons per 100 gallons after heavy use or weekly to oxidize contaminants.

    Application Tips:

    • Always add chemicals to water, never water to chemicals
    • Broadcast granules across the water surface with jets running
    • Wait 15-20 minutes before entering the spa
    • Test water regularly with test strips or a test kit

Frequently Asked Questions

  • For routine maintenance, add chlorinating granules daily or every other day to maintain 3-5 ppm free chlorine. Test your water 2-3 times per week and adjust as needed based on usage and bather load.
  • Chlorinating granules (dichlor) dissolve quickly and are pH-neutral, making them ideal for hot tubs. Chlorine tablets (trichlor) dissolve slowly, are more acidic, and are designed for pools. Always use spa-specific chemicals in your hot tub.
  • No. Pool chlorine products like trichlor tablets or calcium hypochlorite are not formulated for hot tub use and can damage equipment, cloud water, or cause pH imbalances. Always use spa-specific chlorinating granules.
  • Store in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed and away from other chemicals, especially acids. Store out of reach of children and pets.
  • Hot Tub Things® Chlorinating Granules are formulated to be pH-neutral, causing minimal impact on your water balance. However, always test and adjust pH as part of your regular maintenance routine.
  • Yes, chlorinating granules can be used in saltwater systems for shock treatments or to supplement chlorine production during heavy use periods.
