Water Chemistry
The table below summarizes the levels that are recommended by The Association of Pool and Spa
Professionals (APSP). The only special requirements for the AquaRite are the salt level and stabilizer.
It is important to maintain these levels in order to prevent corrosion or scaling and to ensure maximum
enjoyment of the pool. Test your water periodically. Your Authorized AquaRite Dealer or most pool
stores can provide you with the chemicals and procedures to adjust the water chemistry. Be sure to
tell the pool store that you are using an AquaRite
chlorine generator
.
Saturation index
The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the
pool water "balance". Your water is properly balanced if the Si is 0 ±.2. If the Si is below -0.2, the
water is corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2,
scaling and staining will occur. Use the chart below to determine the saturation index.
