Pool Water Chemistry, Conditions and Precautions
6. Metals - Some metals, i.e. copper and iron, can cause loss of chlorine. Also, metals can stain your
pool. Metals can also damage the IntelliChlor
metals and recommend methods of removal.
7. Nitrates and Phosphates can cause extremely high chlorine demands and will deplete chlorine from
your swimming pool. In some cases nitrates may even lower your chlorine levels to zero. Your local
pool professional can test for nitrates and phosphates. While a 0 ppm level of nitrates is the ideal, the
pool owner should make sure that nitrates DO NOT exceed 10 ppm. Phosphates should not exceed
125 parts per billion (ppb).
Optimum Pool Water Chemistry Conditions for Salt Water Pools
(using the IntelliChlor SCG)
In accordance with the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the
following pool water chemistry conditions be maintained on an on going basis to help protect pool users, pool
related equipment and surfaces in and around the pool. These values are important to maintaining the pool
equipment in proper operating condition and preventing corrosion. For more information, refer to your local
agency having jurisdiction, NSPI (National Spa and Pool Institute), the CDC (Centers for Disease Control), or
the WHO (World Health Organization).
Free Chlorine: 2.0 - 4.0 ppm. Above 4.0 ppm may cause corrosion of metal components
Combined Chlorine (Chloramines): None (super chlorinate to remove all chloramines)
pH: 7.2 - 7.8 (USE MURIATIC ACID to lower pH and Soda Ash to raise pH.)
Cyanuric Acid:
Total Alkalinity:
Calcium Hardness:
TDS (includes salt):
Salt:
Metals (Copper, Iron, Manganese):
Nitrates:

Covered Pools and Vinyl Liner Pool and Lowering Chlorine Output Levels
When using the IntelliChlor SCG with covered pools and/or vinyl liner pools, less chlorine is needed. It is
recommend to lower the chlorine output level while the pool is covered. For more information about chlorine
output levels, see "More or Less Output Buttons" page 8.
