Swimming pools Used to adjust pH UP
In pools the correct water chemistry is essential to maintaining a consistent swimming pool environment. The pH is a critical part of this chemistry. If your pH is too low your pool water may become acidic, chlorine residuals dissipate rapidly, eye irritation may occur as well as corrosion to metal fittings, pump impellers, and heater cores. Low pH also causes a rapid loss of alkalinity.
To avoid problems listed above, pH should always be maintained between 7.2 and 7.8. The most desirable level for pH is between 7.4 and 7.6. If pH is too low - run alkali demand test if available. Raise pH by adding soda ash (sodium carbonate). Never add more than 2 lbs per 10,000 gallons in a single treatment. Be sure the pump is running when chemicals are added. Allow to recirculate then retest to determine if further treatment is necessary.
If problems with low pH persist, it is sometimes necessary to INCREASE total alkalinity to stabilize the pH.
