Preparing Pool/Spa Water
Salt Chlorination
The AquaRite S3 automatically converts salt into free chlorine which kills bacteria and algae in the
pool/spa. Chlorine will revert back to sodium chloride after killing bacteria. These reactions will
continuously recycle, virtually eliminating the need to add sanitizing chemicals to your pool/spa.
The only time you may need to add more salt to the pool/spa is when water is replenished due to
backwashing, draining, or splashing (not evaporation). The actual amount of chlorination required to
properly sanitize a pool varies due to bather load, rainfall, temperature, and the pool’s cleanliness.
Water Chemistry
This table summarizes the levels that are rec-
ommended by the Association of Pool and Spa
Professionals (APSP). The salt level listed below
is a recommendation which allows for effective
chlorine generation but generally stays below
the level of human taste. If running higher levels,
note that swimmers may taste the presence of
salt.
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 ± 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.

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.
