4.6.3
How Much Salt to Use
Use salinity test strips, a TDS/salinity meter, or another reliable method to test the salinity of the pool water. Once the
existing salinity has been established, use Table 1 to determine the amount of salt to add to reach the desired level. Be
conservative when adding salt as it is easier to add more if needed than it is to dilute if there is too much salt.
•
4,000 ppm of salt is recommended for optimum water conditions.
NOTE
In cooler water conditions (less than 18°C [65°F]), it may be necessary to add more than 4,500 ppm of salt to keep
the “Check Salt” alarm from appearing on the power pack.
•
Low salt concentration below 3,000 ppm will cause premature cell failure.
•
High salt concentration above 6,000 ppm may cause corrosion damage to pool fixtures.
CAUTION
It is important to note that certain materials used in and around swimming pools and spas may not be compatible with
chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
Zodiac Pool Systems, Inc. does not warrant or guarantee that the chlorinated water generated by the Zodiac AquaPure Ei
Series APURE35C chlorine generating device will not damage or destroy certain types of plants, decking, coping and
other materials in and around your pool and/or spa. Before selecting materials to be used in and around your pool and/or
spa, please discuss all options with your contractor to assess the compatibility of such materials and chemicals.
When mixing acid with water,
ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
Some helpful considerations may include:
•
Maintaining high salt and chlorine levels above recommended range can contribute to corrosion of pool or spa
equipment.
•
Choosing plants that can withstand splash out of pool water containing chlorine and/or salt and other water purification
chemicals.
•
All metal components used in and around a pool should be of a high grade, quality stainless steel.
•
Careful selection of masonry products. The porosity and hardness of natural stones varies greatly. Therefore we
recommend you consult with your builder or stone contractor on the best choice for stone materials around your pool or
spa.
•
Sealing all masonry products. Professionals in the stone industry specify that even natural stone, especially when used
outdoors, be sealed to prevent weathering, staining, and premature degradation. Consult with your stone or deck
contractor for the proper sealer for the masonry products you have selected to use around your pool or spa.
•
For the optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on a schedule per the
manufacturer’s instructions.
•
Use of chemicals other than those recommended may be hazardous. Follow the chemical manufacturers
instructions.
