Sodium bicarbonate, commonly known as baking soda, is frequently used to raise the total alkalinity of swimming pool water. Maintaining proper total alkalinity (typically between 80 and 120 parts per million) is essential for pH stability and effective sanitation. Adding this common household product can help prevent pH fluctuations, which can lead to issues such as scaling, corrosion, and eye irritation. For example, if a pool’s total alkalinity is low, adding a calculated amount of sodium bicarbonate can bring it within the ideal range.
Balanced pool chemistry is crucial for bather comfort, equipment longevity, and the efficacy of chlorine-based disinfectants. Using sodium bicarbonate offers a cost-effective and readily available solution to low alkalinity. Historically, various chemicals have been employed to manage pool chemistry, but the affordability and gentle nature of sodium bicarbonate have solidified its place as a popular choice. A properly balanced pool, with sufficient total alkalinity maintained by appropriate additions, requires less frequent adjustments and minimizes the risk of chemical imbalances.
