Product Details

Product Description:

Pure-Spa Chlorine Tablets offer a slow-dissolving sanitiser designed to maintain clean and healthy spa water. These 20g trichlor tablets continuously release chlorine into the water, controlling bacteria and organic contaminants for safe and hygienic bathing. Suitable for use in a floating dispenser or inline dosing pod (such as the Cloud+), they help maintain a steady chlorine level of 3-5 ppm, ensuring effective water treatment over several days.

Why Use Chlorine Tablets?

Chlorine is the most widely used sanitiser for spas and hot tubs due to its effectiveness in killing bacteria and breaking down contaminants. These tablets provide a trickle-feed of chlorine, meaning fewer manual adjustments compared to granules. The slow-dissolving formula ensures a consistent level of chlorine, reducing fluctuations and making spa water management easier. While chlorine is highly effective, some users with sensitive skin or those who prefer a lower-odour option may find bromine a gentler alternative.

Usage Instructions:

  • Use in a floating dispenser or inline dosing pod. Never place directly into the spa or skimmer.
  • Test chlorine levels daily to maintain an ideal range of 3-5 ppm before each use.
  • Dosing Guide:
    • 1,000L: 2-3 tablets
    • 1,500L: 3-4 tablets
    • 2,000L: 4-6 tablets
  • Adjust the flow regulator on the dispenser to achieve the desired chlorine level.
  • Remove the dispenser when the spa is in use and place it in a bucket of water.
  • Check and replenish the floating dispenser every 3 days to ensure tablets do not fully dissolve before replacement.

These tablets dissolve over 5-7 days, depending on water temperature and flow rate. Always store spa chemicals in a cool, dry place, away from other chemicals.
