Understanding the Chemistry of Pool Water
Keeping a swimming pool clean and safe requires understanding the chemistry of the water. The pH level, alkalinity, and chlorine levels are key factors in maintaining a healthy pool. pH is the measure of how acidic or basic the water is, and it should be between 7.2 and 7.8. Alkalinity is the ability of the water to resist changes in pH, and it should be between 80 and 120 parts per million (ppm). Chlorine is used to kill bacteria and other harmful organisms in the water, and it should be between 1 and 3 ppm.
The chemistry of pool water can be affected by a variety of factors, including weather, usage, and contaminants. Understanding how these factors can impact the water chemistry is essential for keeping the pool clean and safe for swimmers.
Factors Affecting Pool Water Chemistry
