POOL MAINTENANCE & CHEMICAL DEFINITIONS
MAINTENANCE
• Donotaddpoolchemicalsdirectlytotheskimmer.Thismaydamagethecell.
•Maintainingahighsaltandsanitizerlevelsaboverecommendedrangecan
contribute to corrosion of pool equipment.
• Checktheexpirydateofthetestkitasthetestresultsmaybeinaccurateifthe
kit is used after that date.
• If,duetoheavypoolusage,itisrequiredtoincreasethesanitizerlevel,thenuse
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.
Resultiftoolow- Corrodedmetals,eye&skinirritation,
destruction of total alkalinity.
Result if too high - Scale formation, cloudy water, shorter
filterruns,eye&skinirritation,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.
Resultiftoolow- Corrodedmetals,eye&skinirritation.
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&skinirritation,poorChlorine
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)
