What are the main factors that affect water balance in pools?

Water balance in pools is critical for maintaining a safe, comfortable, and clean swimming environment. The main factors that affect water balance include pH, alkalinity, and hardness, as these chemical properties have a direct impact on the water quality and the effectiveness of sanitizers.

pH is a measure of how acidic or basic the water is. The ideal pH range for pool water is typically between 7.2 and 7.8. If the pH is too low, it can cause corrosion to pool equipment and irritate the skin and eyes of swimmers. If it's too high, it can lead to calcium scale formation and reduce the efficiency of chlorine in killing harmful microorganisms.

Alkalinity acts as a buffer for pH, helping to stabilize it against any fluctuations. The total alkalinity of the water should be maintained within a specific range (usually between 80-120 ppm). Proper alkalinity prevents rapid changes in pH, thus maintaining a balanced environment for swimmers.

Hardness refers to the concentration of calcium and magnesium in the water. Maintaining appropriate hardness levels is essential because low hardness can cause corrosion of pool surfaces and equipment, while high hardness can lead to scale formation.

These three factors are interrelated and collectively influence the overall water
