Save yourself the future troubles and stockpile on our Wave Spa 5kg Chlorine Granules to ensure year-round chlorination. A must-have disinfectant for your Wave Spa hot tub, our granules are completely soluble and have little effect on pH, containing a stabiliser to protect against loss of chlorine to sunlight, making them ideal for daily chlorination.

How do I use chlorine granules in my hot tub?

Dilute 1 + 1/2 heaped teaspoons (Approx 12g) WAVE™ Chlorine Granules into 10 cubic litres of fresh water using a clean plastic container and mix carefully. Slowly pour the solution into the spa close to the return inlets and rinse out the container thoroughly.

This daily dose rate is offered as a general guide for your Wave hot tub, please note that regularly used spas or those maintained at higher temperatures may require increased dosage. Test for actual requirements by using our 3 in 1 testing kit - adjusting the dose rate as necessary to maintain a chlorine level of 1-3 ppm or mg/litre.

pH Control

To obtain maximum benefit from WAVE™ Chlorine Granules 55%, the pH of the water should be maintained around 7.4 and between 7.2 and 7.8 at all times. Chlorine is less effective at high pH ie. above 7.8.

It’s a good idea to ensure everyone using your tub showers before getting in, creams, fake tan, deodorant etc. are not your tubs friend.
