POOL MAINTENANCE & CHEMICAL DEFINITIONS
Consult with local swimming pool dealer for water treatment.
• Donotaddpoolchemicalsdirectlytotheskimmer.Thismaydamagethecell.
•Maintainingasaltandsanitizerlevelabovetherecommendedrangecancontributetothe
corrosion of the 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 trichlor, TCCA or dichloro.
Preferred Water Chemistry Reading
Minimum Ideal Maximum
Free Chlorine
0 0.5 - 3.0 ppm 5.0 ppm
Combined Chlorine
0 0 ppm 0.2 ppm
pH
7.2 7.4 - 7.6 7.8
Total Alkalinity
40 ppm 80 ppm 120 ppm
Calcium Hardness
50 ppm 100 - 250 ppm 350 ppm
Stabilizer (Cyanuric Acid)
10 ppm 20 - 40 ppm 50 ppm
Free Chlorine
-
Is the chlorine residual 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 - 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.
