What is the relationship between pH and alkalinity in maintaining proper water balance in a pool?

The relationship between pH and alkalinity in maintaining proper water balance in a pool is that they are interconnected. pH measures the acidity or basicity of the water, while alkalinity measures the water's ability to resist changes in pH. Proper alkalinity levels help stabilize pH, ensuring it stays within the ideal range for pool water. This balance is crucial for water clarity, swimmer comfort, and the effectiveness of pool chemicals.
