FAQs

How often should I use these granules?

You should use them as part of your daily or weekly maintenance routine, or after each use of the spa, based on the test results from your water test kit.

Can I use these in a pool?

These granules are specifically formulated for spas and hot tubs. While they work on the same principle as pool chlorine, the concentration is tailored to the smaller water volumes found in spas.

Is it safe to get into the water immediately after adding granules?

It is recommended to wait at least 30 to 60 minutes after application to allow the granules to dissolve and circulate fully throughout the system.

Do I need to check pH levels separately?

Yes, maintaining the correct pH (usually 7.2 to 7.6) is critical for chlorine to be effective. Always test both chlorine and pH.

How should I store this product?

Keep the container in a cool, dry, dark place out of reach of children and pets, and ensure the lid is properly secured to prevent moisture contamination.

Troubleshooting

Water remains cloudy after dosing

Check your pH and total alkalinity levels. If these are unbalanced, the chlorine will not work effectively.

Chlorine levels are consistently too high

Cease dosing and keep the spa cover off to allow the chlorine to dissipate naturally, then re-test before next use.

Granules not dissolving immediately

Ensure the circulation pump is active. If the water is very cold, consider dissolving the granules in a bucket of warm spa water first before pouring.

Pros and Cons

  • Effective at killing bacteria and microorganisms
  • Stabilised to withstand heat and light exposure

Setup, Compatibility & Care

To use, ensure your hot tub circulation pump is running, then broadcast the required amount of granules across the water surface. Always test your water using a reputable test kit or strips before and after application to confirm chlorine levels are within the recommended range (typically 3-5 ppm for hot tubs). Store the container in a cool, dry, and well-ventilated area away from direct sunlight, ensuring the lid is tightly sealed at all times. Keep the granules away from other chemicals, particularly acids or strong alkalis, to prevent dangerous reactions.
