Switching to a swimming pool ozonator may seem intimidating at first, however ozone has long been used as a simple way to keep pool water clean. Typically, switching to ozone can result in reduced chemical usage by up to 95%.
If a high concentration of any mineral (such as calcium or iron) exists in the water, it is necessary to treat it before starting the ozone system.
This should be required only when the pool is drained and refilled. If the water is clean and clear, the ozone system may be started immediately. If the water is dirty and cloudy, it is recommended that it is drained and the filers thoroughly cleaned before refilling and starting the system.
It is not recommended that an in-ground pool be drained in the winter or after the first rain of a season. Use a shock treatment instead of draining to avoid the possibility of severe damage resulting from “floating” the pool out of the ground.
Ozone and Bromine
Ozone has a short half-life which means it dissipates and re-transforms into oxygen very quickly. Therefore, a small residual of another disinfectant must be maintained. We recommend the use of bromine in indoor pools. Bromine residual will act as a buffer when the ozone system is not operating. Bromine needs to be maintained only 1.0 PPM (Parts Per Million) so that the trace amount of the product in the water will not be noticed. Chlorine will also work as a residual oxidizer and may be used effectively in conjunction with the ozone system.
Ozone and Chlorine
For outdoor pools, we recommend the use of chlorine to supplement the ozone. Chlorine residual will act as a buffer when the ozone system is not operating. Chlorine needs to be maintained at 1.0 to 2.0 PPM (Parts Per Million). 11 Water Preparation To properly prepare the water for the ozone system, make the following adjustments and maintain the levels outlined below: Bromine 1.0 PPM Chlorine 1.0 to 2.0 PPM and pH 7.2 to 7.6 Total Alkalinity 100 to 150 PPM Calcium Hardness 200 to 350 PPM
If any unusual reactions are experienced when ozone is introduced into the water (such as abnormal color or odor), please wait a few days to give the ozone and filter system time to work.
Always maintain the recommended residual levels of bromine or chlorine (at least 1.0 PPM) to help control algae formation. Brushing the poolside once a week is also effective. Additionally, using an algaecide is effective. Shock Treatment If an unusually high bather load causes cloudiness in the water, it is recommended that a chlorine shock treatment be used to assist the ozone in cleaning the water. Routine, periodic shocking is recommended to prevent buildup of organic contaminants, especially with indoor pools.
