Aqua Sparkle Spa Stabilised Chlorine Granules are the most popular sanitiser for Hot Tubs, Spas and Outdoor Pools. They can be used for daily dosing of your spa or hot tub, to produce free active chlorine which kills bacteria and other potentially harmful organisms.


Your spa or hot tub water should be chlorinated at all times, never allow your spa or hot tub to be used without first testing the water to make sure it contains the correct amount of chlorine.



Aqua Sparkle Spa Stabilised Chlorine Granules provide an economical semi-automatic Chlorination of your spa water. Aqua Sparkle Spa Stabilised Chlorine Granules are 55% available Chlorine and are completely soluble. As they contain Cyanuric Acid they are automatically stabilised against destruction of chlorine residual by sunlight.


Aqua Sparkle Spa Stabilised Chlorine Granules adds chlorine to the water just like any other sanitiser but it also adds stabiliser at the same time. It has a pH close to neutral (7) so that it will have little effect on the pH of the spa water.
