RECOMMENDATIONS FOR

POOL WATER QUALITY

Chlorine reading should be 1.0 – 3.0 Parts Per Million (ppm) for unstabilized chlorine and 2.0 – 5.0 ppm for stabilized chlorine.

pH should read between 7.2 – 7.8. a low pH level (acidic) can result in corrosive water while a high level ( alkaline) results in scaling water. Swimming in water that is not in the 7.2-7.8 range may lead to skin and eye irritation problems.

Calcium Hardness should be between 200-400 ppm. Low calcium hardness can cause corrosive water while high calcium hardness can cause scaling water.

Total Alkalinity should be between 80-120 ppm. Total alkalinity is the measure of the water’s ability to resist changes in pH. It is the governor of pH. Low total alkalinity can lead to corrosive water while high total alkalinity can cause scaling water.

Cyanuric Acid (stabilizer) should not exceed 80 ppm. If the Cyanuric acid exceeds 80 ppm, action must be taken to reduce the level. Stabilizers help to reduce the depletion of chlorine by sunlight, however it also causes the chlorine to become less effective as an oxidizer and sanitizer. When using stabilized chlorine, higher levels of chlorine must be maintained.

Please follow the manufacturers guidelines when handling water treatment chemicals.
