Q. What is ozone?
A. Ozone is a sky-blue gas formed naturally by the action of the sun’s ultraviolet rays, or when a large electrical discharge, like lightning, passes through oxygen.
Used for many years in the US and Europe, ozone is the standard purifier in water bottling plants and pools approved by the Olympic Federation.
It’s highly toxic, however. Therefore, all traces of ozone must be consumed or removed prior to it reaching the pool, so small amounts of residual sanitiser like chlorine or bromine must be used to provide continuous protection in the pool. Due to its instability it remains in water for a short time and has no effect on pH or water balance. It can also reduce the need for shock dosing.
