Hot Tub Chlorine Sanitisers for Healthy Bathing

We have selected the following ‘Quality Approved’ hot tub chlorine sanitisers as suitable for all hot tubs and spas.

We advise hot tub chlorine mini tablets (20g) for use in acryllic hard shell hot tubs for minimum hassle maintenance. But if you have a vinyl hot tub like many of the popular inflatable spas available, we recommend using hot tub chlorine granules instead. Chlorine granules are fast dissolving, which allows gasses to escape prior to replacing the cover. This prevents bleaching of the walls above the water line over time. For more information please read our guide regarding the different types of hot tub chlorine and how to use them.

All the hot tub chlorine in this category is "stabilised", designed to give you a longer period of protection between doses. For problem solving and dealing with murky or green water see also our non-stabilised shock chlorine, which is designed to burn off quickly after super-dosing the hot tub allowing you to re-use the hot tub sooner.

The following spa chlorine granules are fast dissolving high quality grade 1 chlorine products from reputable brands.

Please note: Always use chlorine spa test strips when sanitising with hot tub chlorine. Test before you get in and dose when you get out!
