Sodium bicarbonate is frequently used to raise the total alkalinity of swimming pool water. Typically, one to two pounds per 10,000 gallons will increase total alkalinity by about 10 ppm. However, the precise amount needed depends on the current water chemistry, the desired alkalinity level, and the pool’s volume. Testing the water before and after adding any chemical is crucial for proper pool maintenance.
Maintaining proper alkalinity is essential for swimmer comfort and equipment longevity. Balanced alkalinity buffers pH fluctuations, preventing rapid changes that could irritate skin and eyes or damage pool liners and equipment. Historically, maintaining proper water chemistry relied on less precise methods. The development of readily available testing kits and refined chemicals like sodium bicarbonate has significantly improved pool maintenance, making it easier to achieve and maintain ideal water balance.
