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.
