Ozone pools use ozone as the primary sanitizer instead of chlorine or bromine. Ozone is a highly reactive gas that oxidizes organic matter, including bacteria and other microorganisms. It is also effective at removing dissolved metals, such as iron and copper, from the water.

The ideal ozone level for a pool is between 0.5 and 1.0 parts per million (ppm). This level is high enough to be effective at sanitizing the water, but low enough to avoid causing skin or eye irritation.

In addition to ozone, ozone pools also require a pH level between 7.2 and 7.6, and an alkalinity level between 80 and 120 ppm. These levels help to protect the ozone from breaking down and also help to prevent the formation of scale on the pool surfaces.

Ozone pools can be a great option for people who are looking for a more natural way to sanitize their pool. They are effective at removing bacteria and other contaminants, and they are also less likely to cause skin or eye irritation than chlorine or bromine.

Here is a more detailed look at the chemical levels in an ozone pool:

* Ozone: 0.5 to 1.0 ppm

* pH: 7.2 to 7.6

* Alkalinity: 80 to 120 ppm

* Calcium hardness: 200 to 400 ppm

* Cyanuric acid: 0 to 10 ppm

These levels should be checked regularly and adjusted as needed to ensure that the pool water is safe and clean.
