Water Chemistry

The table below summarizes the levels that are recommended by Hayward. The only special
requirements for the AquaRite Pro 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 Pro 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 Pro 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.

How to use: Measure pool pH, temperature, calcium hardness, and
total alkalinity. Use the chart above to determine Ti, Ci and Ai into the
above equation. If Si equals 0.2 or more, scaling and staining may
occur. If Si equals -0.2 or less corrosion or irritation may occur.
