Free Chlorine
-
Is the chlorine residual present in pool water.
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.
(Cyanuric Acid)

• DO NOT add pool chemicals directly to the skimmer. This may damage the cell.
• Maintaining high salt and chlorine 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 chlorine is required due to heavy bather load, use a pool sanitizer
based on Trichloro-s-triazinetrione or sodium dichloro-s-triazinetrione dihydrate.
