What is a Hot Tub Ozonator?
Ozone is a strong natural oxidizer which breaks down chemicals and bodily fluids, including:
- hair spray
- body lotion
- hand cream
- suntan lotion
- saliva and urine
When used in conjunction with your regular sanitizer, ozone helps kill pathogenic bacteria, germs, and viruses, as well as oxidizing organic contaminants. This leads to dramatically better water quality than you would have with just chlorine or bromine alone.
How it Works in Hot Tubs
Hot tub ozonators produce ozone by splitting oxygen molecules apart into two free oxygen atoms through the use of intense UV light, or by corona discharge (CD) within the ozonator unit. When the freed oxygen atoms collide with an oxygen molecule, they merge and form ozone which effectively works to breakdown contaminants in water. This results in clearer, cleaner water.
Ozonators Save Money
Ozone frees up combined chlorine and bromine, allowing them to be continuously reused. Ozone ultimately enhances the effectiveness of bromine and chlorine as well as many natural alternative sanitizers.
Because of this, you generally need to add less sanitizing chemicals to your water, saving you time and money.
The amount of ozone produced by a hot tub ozonator is insignificant to the normal atmosphere we live in. When dissolved in water, ozone is extremely safe. Excessive ozone quickly coverts back to oxygen.
Pros & Cons of Ozone
Ozone not only destroys microorganisms, but also breaks down harmful chemicals, and causes total dissolved solids to clump together for easier removal by your filter cartridge. The result is not just cleaner & clearer water, but also water which feels smoother to the skin.
It is important to note that although ozone is very effective and safe for your hot tub equipment, it can reduce the life of the hot tub cover underside vinyl.
The use of a floating blanket provides an extremely effective barrier to protect your cover, while also providing significant energy savings!
Deciding Between CD or UV
As mentioned above, there are two different types of ozonators available for hot tub use: CD (corona discharge) and UV ozonators. UV ozonators are waning in popularity due to their higher energy usage, especially with new CD technology raising new standards for longer life, effectiveness, and lower costs.
