GOOD - Ozone
Ozone is natures cleanser and is 1000 times more powerful than chlorine in its ability to oxidize foreign matter including oils, and bacteria that can quickly form in a hot tub. It is the most effective sterilizer known to man, killing bacteria and viruses on contact. Ozone is made up of 3 oxygen molecules (O3) instead of two. Once Ozone is used up (oxidized) it reverts to pure O2 leaving no residual by products. Ozone is commonly used in municipal water treatment plants or in water dispensers found in grocery stores.
Northern Lights Cedar Tubs strongly recommends using an ozonator in all our hot tubs to ensure clean safe water!
