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
®
Salt Chlorine Generator. Have your local pool
professional check for 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 Salt Chlorine Generator )
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, liming or other problems. The IntelliChlor
Salt Chlorine Generator is warranted to operate properly only if these conditions are met. 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: 1-3 ppm for pools and 3-5 ppm for spas. 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 for pools and spas)
Cyanuric Acid: 30 ppm - 50 ppm
Total Alkalinity: 100 ppm - 120 ppm for pools and spas
Calcium Hardness: 200 ppm - 300 ppm for pools / 150-200 for
spas TDS (includes salt): 3000 ppm minimum to 5700 to 6000 maximum
ppm Salt: 3000 ppm - 4500 ppm (ideal 3400 ppm)
Metals (Copper, Iron, Manganese): None
Nitrates: None
Phosphates: Less than 125 ppb
Saturation Index -.3 to .3 (zero (0) best)
Covered Pools and Vinyl Liner Pool and Lowering Chlorine Output Levels
When using the IntelliChlor Salt Chlorine Generator 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.
