Product Description

Clearwater 1kg Chlorine Granules are used for sanitising your spa or pool and maintaining a healthy hot tub environment. The chlorine granules disinfect the water by killing bacteria; they are quick dissolving and relatively pH neutral.

Chlorine Testing

You can use Clearwater Dip Tests to check the chlorine and pH levels in your hot tub. You should test the water before every use to check that the chemical levels are correct and safe and also that the pH is between 7.6 and 7.2.


If you need to increase the amount of chlorine in your hot tub, then this can be achieved by sprinkling the chlorine granules directly in to your spa water (if your water temperature is over 20°C) or alternatively by pre-diluting in a container of warm water (this method should always be used if your applying to a hot tub with a water temperature of under 20°C). Try adding chlorine a little at a time to prevent over chlorination.

If you hot tub becomes over chlorinated then you should wait for the chlorine level to naturally drop (this will happen on its own over a period of days) and re-test before using.

Managing pH levels

For Chlorine Granules to work effectively and efficiently, the pH levels in your hot tub must be kept at the optimum level. Clearwater Dip Tests can also be used to test the pH levels in your spa. The optimum pH level for your hot tub is between 7.6 and 7.2.

If the pH of your spa water is above 7.6 then use Clearwater pH Minus to reduce it, using the application instructions on the bottle. If the pH of your spa water is below 7.2, then use the Clearwater pH Plus to increase it, using the application instructions on the bottle.
