A saturation index of 0 is perfectly balanced
A negative saturation index has corrosive tendencies
A positive saturation index has scaling tendencies
A saturation index of +0.3 or -0.3 is ideal

measure at 1,000 ppm or greater
4.4 Optimum Pool Water Conditions
In accordance with the Association of Pool and Spa
Professionals
®
(APSP
®
) standards, we recommend the
following water balance conditions be maintained on
an on-going basis to protect the pool nish and the
equipment and to ensure the pleasing appearance of
the water. The Jandy Pro Series is warranted to operate
properly only if the following conditions are met:
Free Chlorine: Ideal levels should be 1.0 - 3.0 ppm.
Combined Chlorine (Chloramines): None. Use shock
(fast dissolving chlorine to remove all chloramines).
pH: 7.4 - 7.6 (Use muriatic acid to lower pH and soda
ash to raise pH).
Chlorine Stabilizer (Cyanuric Acid): 30 - 50 ppm (for
outdoor pools only).
Total Alkalinity: 80 - 120 ppm (U.S.); 100 - 120 ppm
(Canada)
Calcium Hardness: 200 - 400 ppm
Metals (Iron, Manganese): None
Nitrates: None
Phosphates: None
Temperature: Above 60ºF (16ºC)
chlorination. If diminished water clarity or evidence
of algae persists, your local pool dealer may suggest
additional steps to sanitize your pool water and
eliminate chloramines.
NOTE On initial startup of a pool, it is best to shock using an
alternate source, i.e., use a shock treatment
available at your local pool supplier.
Proper Water Balance is key to your enjoyment of your
pool or spa experience and to the long life of your cell.
• The pH of your pool or spa’s water is the measure
of whether water is either acidic or scale forming.
Cold water is typically more acidic, while hot
water is more scale forming. The ideal range for
pH in either a pool or a spa is 7.4 to 7.6 regardless
of temperature. If pH is allowed to rise, above 7.6
and the chlorine generator is operating, calcium in
the water may coat the metal plates in the cell. This
could restrict the ow of water resulting in reduced
efciency and possibly damage the cell. If the pH
is allowed to drop below 7.4, the water will become
more acidic and will dissolve the metal components
in the pool plumbing with the metal plates in the cell
being a prime target.
• Total Dissolved Solids (TDS). Adding salt to pool
water will raise the TDS level. While this does not
adversely affect the pool water chemistry or clarity,
the pool water professional testing for TDS must be
made aware salt has been added for the sanitizing
system. The individual performing the TDS test will
then subtract the salinity level to arrive at the correct
TDS level.
• New pool water in a recently lled or newly
renished pool may contain undesirable matter
which could interfere with the salt water
chlorinator’s ability to sanitize properly. Make
sure the water is tested by a pool professional and
properly balanced before turning on the chlorinator
system. New plaster pools have a constant acid
demand for six (6) months. Test often and maintain a
proper pH to avoid excess scaling of the cell.
• Langelier Saturation Index is a standard
method of determining the potential of your
