Water Balance Factors
pH
PH is the most important factor in water balance. The pH is a measurement of the relative acid or base of the water. If water falls out of balance on the low side, it becomes corrosive, attacking pool surfaces and equipment. If it should rise out of balance on the high side, scale build-up can occur leaving unsightly deposits. Readings between 7.4 and 7.6 are considered acceptable for swimming pool water. Test the pH at least twice a week during the summer season. Daily testing is recommended.
Total Alkalinity (TA)
Total Alkalinity is a measure of the alkaline materials dissolved in the water, which helps keep the pH at the proper level. The waters ability to resist pH changes depends on the amount of this alkaline material in the water. The recommended Total Alkalinity range for gunite pools is 100-150 ppm and vinyl pools 125-175 ppm. If the Total Alkalinity is low, the result is pH will bounce in and out of range. If Total Alkalinity is too high, it becomes very difficult to adjust the pH as needed. Testing the Total Alkalinity is recommended about twice a month.
Calcium Hardness (CH)
Calcium Hardness refers to the amount of dissolved minerals in the water. Proper Calcium Hardness levels for gunite pools range between 200-275 ppm and 180-250 ppm for vinyl pools. A low Calcium Hardness can lead to corrosion of equipment or etching of a plaster finish. Calcium Hardness too high causes cloudy water and scaling. Test Calcium Hardness levels at least monthly during the summer season.
Stabilizer (Cyanuric Acid – CYA)
Sunlight causes the amount of chlorine in your pool water to decrease. Stabilizers (Cyanuric Acid) protect the chlorine from the sun’s rays increasing the life efficiency of the chlorine. Proper Cyanuric Acid levels range between 30-50 ppm. Monthly testing is recommended.
