POOL MAINTENANCE & CHEMICAL DEFINITIONS
Consult with local swimming pool dealer for water treatment.
• 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 trichlor, TCCA or dichloro.
Preferred Water Chemistry Reading
Minimum Ideal Maximum
Copper Ions 0 0.1 - 0.2 ppm 0.2 ppm
Free Chlorine 0 0.5 - 3.0 ppm 5.0 ppm
Combined Chlorine 0 0 ppm 0.2 ppm
pH 7.2 7.4 - 7.6 7.8
Total Alkalinity 100 ppm 100 - 140 ppm 140 ppm
Calcium Hardness 150 ppm 200 - 400 ppm 500 - 1000 ppm
Stabilizer (Cyanuric Acid) 10 ppm 20 - 40 ppm 50 ppm
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 and magnesium 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.
