Many pool owners become disappointed with the results and costs of Ozone Generators. Ozone generators use a special ultra-violet light to kill bacteria. Like the cartridge systems, ozone generators only kill contaminants in the ozone chamber and provide no residual protection to the water in the pool, the sanitization benefits are short lived, 15-30 minutes in general. To be effective, the pool pump must run 24 hours a day. Ozone units designed for swimming pools are very expensive and draw a lot of electric current. These units are better suited for spas but are not practical for the volume of water in most swimming pools.
Even the best ozone generator unit will not totally eliminate the need for chlorine or other chemical oxidizing agents in the pool water.
