Testing is important prior to using your hot tub.


We provide the complete range of hot tub sanitisers, so the choice is yours! Chlorine is the most affordable, but many users prefer to use Bromine which works better in a warm water environment. Some people also prefer the odour to that of chlorine. Active Oxygen is popular among those with very sensitive skin, but comes at a premium.
