POOL MAINTENANCE & CHEMICAL DEFINITIONS
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.
HCLO - A very effective killer of algae and bacteria known as hypochlorous acid.
Free
Chlorine
-
Is the sanitizer (HCLO) 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 alka
linity 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 - Eye & skin irritation, difficulty balancing water and
poor chlorine efficiency. Scale will form and will
cause the water to become cloudy.
Stabilizer
-
Stabilizers extend the life of Chlorine in swimming pools.
