It is important to keep the pool balanced because it affects: operation, the condition of the pool equipment, longevity of pool surfaces, and positive bather experience.
What Happens When:
High Low
Chlorine 2.0-4.0ppm |
Eye/Skin Irritation Lung Irritation Corrosion of Metals Etching and Deterioration of Surfaces Heater Failure |
Microbe and Bacteria Growth Algae Growth Chloramines Occur Eye/Skin Irritation Clogged Filters Water Unclean |
PH 7.2-7.8ppm |
Scaling Water Clogged Filters Clogged Heater Elements Reduces Circulation Cloudy Water Metal Staining Chlorine inefficiency Eye/Skin Irritation |
Corrosive Water Etching and Deterioration of Surfaces Corrosion of Metals Staining of Surface Walls Wrinkles in Liners Eye/Skin Irritation Dry Skin |
Alkalinity 80-120ppm |
PH is Unstable Cloudy Water Rough Pool/Spa Surfaces Clogged Filters Clogged Heater Elements Reduced Circulation |
PH Becomes Harder to Control Etching and Deterioration of Surfaces Heater Failure Dry and Itchy Skin |
Calcium Hardness 200-400ppm |
Scaling Water Rough Pool/Spa Surfaces Clogged Filters Cloudy Water Clogged Heater Elements Reduced Circulation Eye Skin Irritation |
Corrosive Water Etching and Deterioration of Surfaces Heater Failure Water starts seeking calcium from other sources- including the surface of pool |
Cyanuric Acid 15-20ppm |
Cloudy Water Affects Alkalinity Readings Outdoor Pool Only |
Cannot Maintain Proper Sanitizer Levels Outdoor Pool Only |
