The following chart shows the ideal ranges that should be kept for your swimming pool to remain at it's best and provides some more detailed information

 Ideal Range
1.0 - 3.0
 Ideal Range
80 - 120 ppm
 Ideal Range
200 - 300 ppm
Free chlorine measures the unused, still effective chlorine in the water
 Measures dissolved alkaline materials in the water
 Calcium hardness measures dissolved minerals in the water
Chlorine sanitizes the water and helps prevent the growth of algae and bacteria
Proper alkalinity levels help the pH remain constant
High calcium hardness causes cloudy water and scale buildup
Chlorine is available in many forms such as tablets, sticks and powder
Low alkalinity can cause pH bounce where the pH levels fluctuate in and out of range
  Low calcium hardness causes corrosion of pool equipment and surfaces
Salt water pools use electrolysis to convert salt into chlorine
High alkalinity indicates hard water and can result in cloudiness
 High calcium hardness can also cause eye irritation

 Ideal Range
7.2 - 7.6
 Ideal Range
35 - 60 ppm
pH measures the acidity of swimming pool water and is measured on a scale of 1 to 14. 7 indicates a neutral pH, lower than 7 indicates acidic water, above 7.8 is very basic/alkaline
Also known as cyanuric acid
pH levels can shift rapidly due to rain, fresh water, swimmer waste and other added chemicals
Extends the life of chlorine up to 3.5x by protecting it from the sun
An ideal pH level is required for other chemicals to work properly. For instance, chlorine effectiveness drops drastically the higher the pH. Chlorine is only 20-25% effective at a pH of 8
Chlorine is able to stay in the water until needed to fight off bacteria, algae, etc.
Incorrect pH levels can damage vinyl liners. High pH greatly lowers life expectancy and causes premature aging. Low pH can result in liner wrinkles. A liner replacement costs on average $2000 - $5000!
Chlorine products such as tablets that are marked "stabilized" contain some cyanuric acid
