Minimum Ideal Maximum
Free Chlorine 0 1.0 - 3.0 ppm 3.0 ppm
Combined Chlorine 0 0 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 30 - 50 ppm 150 ppm
Free Chlorine
-
Is the sanitizer (HOCL) 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
(Cyanuric Acid)
pools.
• Maintaining high salt and sanitizer levels above recommended range can
contribute to corrosion of pool equipment.
• Check the expiry date of the test kit as test results may be inaccurate if used
after that date.
• If additional sanitizer is required due to heavy bather load, use a pool sanitizer
based on Trichloro-s-triazinetrione or sodium dichloro-s-triazinetrione dihydrate.
HOCL - A very effective killer of algae and bacteria known as hypochlorous acid.
