Pool Chemistry - Hayward Aqua Trol AQ-TROL-RJ-CUL Manuel Du Propriétaire

As with any pool, it is important that you maintain chemical makeup of the pool water. The table be-
low summarizes the levels that are recommended by The Association of Pool and Spa Professionals
(APSP). The only special requirement for the Aqua Trol is 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 local pool store 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
Aqua Trol chlorine generator.

Saturation Index
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 equation and chart below to determine the saturation index.

Use: Measure the pH of the pool water, the temperature, water hardness, total alkalinity,
and total dissolved solids. Use the table above to determine Ti, Ci, Ai, and TDS in the
formula shown above. If the Si is equal to 0.2 or more, stains may appear. If the Si is
equal to -0.2 or less, corrosion or deterioration may occur.
