POOL MAINTENANCE & CHEMICAL DEFINITIONS
Water parameters to be maintained as part of daily maintenance
Parameters Swimming Pools
Free available chlorine 1.0 - 3.0 ppm
This level may be lowered to 0.6- 3.0 ppm once the
copper concentration has reached 0.2-0.3 ppm.
pH 7.2 - 7.8
Total alkalinity 100 - 120 ppm
Calcium hardness 200 - 300 ppm
Stabilizer (cyanuric acid) 30 - 100 ppm
Copper levels 0.2-0.3 ppm
Refer to troubleshooting section if copper levels cannot
be maintained
Free Chlorine ‐ Is the chlorine residual present in pool water.
Combined Chlorine ‐ Is formed by the reaction of free chlorine with ammonia wastes.
Result if too high ‐ Sharp chlorinous odor, eye irritation.
pH ‐ A value that indicates how acidic or basic a solution is.
Result if too low ‐ Corroded metals, eye & skin irritation, destruction of total alkalinity.
Result if too high ‐ Scale formation, cloudy water, shorter filter runs, eye & skin irritation, poor
chlorine efficiency.
Total Alkalinity ‐ Indicates the degree of the water's resistance to change in pH. It determines the speed and ease
of pH change, so always adjust total alkalinity before adjusting the pH level.
Result if too low ‐ Corroded metals, eye & skin irritation. Low alkalinity will cause the pH to be
unstable. Any chemical added to the water will have an affect on pH.
Result if too high ‐ Scale formation, cloudy water, eye & skin irritation, poor chlorine efficiency.
Calcium Hardness ‐ Refers to the amount of calcium dissolved in the water.
Result if too high ‐ Scale will form and will cause the water to become cloudy.
Stabilizer ‐ Stabilizers extend the life of chlorine in swimming pools.
(Cyanuric Acid)
• Do not add pool chemicals directly to the skimmer. This may damage the cell.
• Maintaining a salt and sanitizer level above the recommended range can contribute to the corrosion of
the pool equipment.
• Check the expiry date of the test kit as the test results may be inaccurate if the kit is used after that
date.
• If, due to heavy pool usage, it is required to increase the sanitizer level, then use a chemical based on
Trichloro ‐ s ‐ triazinetrione or sodium dichloro ‐ s ‐ triazinetrione dihydrate.
• When replacing the chlorine generating cell and the copper cell, only use replacement cells having a
label that clearly states that it is a replacement cell for the Krystal Clear Saltwater System® Model CS7110.
• The life expectancy to the chlorine and copper electrodes is 3000 hours under normal use conditions.
• Heavy pool usage and higher temperatures may require a higher chlorine output to maintain proper free available chlorine residuals.
