• Do not add pool chemicals directly to the skimmer. This may damage the cell.
• Maintaining a high salt and sanitizer levels above recommended range can
contribute to corrosion of 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.

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 -
Result if too high - Scale formation, cloudy water, shorter

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.

Refers to the amount of calcium and magnesium
dissolved in the water.
Result if too high - Scale will form and will cause the

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.
