Pool water pH is one of the best measures of balanced water. The pH of a human tear is 7.5, so the ideal range for best swimmer comfort is between 7.4 - 7.6. But 7.2 - 7.8 is also considered an acceptable pool water range. Maintaining proper pH levels is essential for swimmer comfort, protection of pool equipment and effectiveness of the chlorine.

Summary: Soda Ash Vs Baking Soda. Soda ash and baking soda can both be used to raise a pool's pH and total alkalinity levels, but they work in opposite ways. Soda ash will raise pH and minimally raise alkalinity, while baking soda will raise alkalinity and minimally raise pH. Use baking soda when the pH isn't off by much, but the alkalinity ...
