The World’s Most Secure Cylinder
It is the owner’s responsibility to ensure the hot tub or swim spa is clean and the water is properly disinfected to prevent the spread of disease. It is important to maintain the proper level of disinfectant to ensure clean and safe water. Chlorine and bromine are the most commonly used disinfectants. The more a hot tub or swim spa is used, the faster the disinfectant in the water gets used up.
Before and after use you should check the disinfectant level and add chlorine or other disinfectant if it is low, even if the hot tub or swim spa will not be used for a while. There are other important measures of water quality, such as pH, that must also be checked and adjusted as necessary. swim spa chemicals should always be used safely and stored in a locked location or out of the reach of children. Your local swim spa supplier may offer water testing services to help you properly maintain water quality by identifying problems, knowing which chemicals to add, and knowing how and when to safely add them.
To help keep hot tubs clean, you should also drain and scrub them with a bleach solution (5ml per 4 liters of water) at least monthly, or more often for heavily used hot tubs. Filters and pumping systems should be cleaned and serviced on a regular basis.
