Hot Tub Chemicals

Welcome to the hot tub chemicals range by Clearwater, the place to buy everything you need to keep your spa water clean and healthy. Whilst Clearwater Chemicals have been designed with Lay-Z-Spa hot tubs in mind, they are also suitable for other types of hot tub water treatment. It is essential to keep your hot tub water hygienic by treating it with chemicals and regularly changing your filters, regardless of how long or how frequently you use your hot tub. Correct water treatment will ensure the safety of the hot tub bathers, reduce how often you have to replace the water and also prolong the lifespan of your pump. For more detailed advice on chemicals, visit our Chemical Guides page.
