How to raise the pH in a swimming pool?

Raising the pH in a swimming pool is essential for maintaining proper water balance and preventing issues such as corrosion, scale formation, and eye irritation. The pH level of pool water should ideally be between 7.2 and 7.6 for optimal swimmer comfort and effectiveness of chlorine disinfection. To raise the pH in a swimming pool, start by testing the current pH level using a reliable pool water test kit. Once you have determined that the pH is below the desired range, follow these steps:
1) Add Sodium Carbonate (Soda Ash) or Sodium Bicarbonate (Baking Soda): Sodium carbonate, commonly known as soda ash, and sodium bicarbonate, also known as baking soda, are commonly used to raise pH in swimming pools. Follow the manufacturer's instructions carefully and add the appropriate amount of the chosen pH increaser to the pool water. It's essential to add the pH increaser gradually and in small increments to avoid raising the pH too quickly.
2) Distribute pH Increaser Evenly: To ensure uniform distribution and avoid localized pockets of high pH, pour the pH increaser slowly around the perimeter of the pool while the pump and filter system are running. This will help circulate the pH increaser throughout the pool water for even mixing.
3) Test pH Regularly: After adding the pH increaser, wait at least six hours and then retest the pH level using a pool water test kit. Repeat the process if necessary until the pH falls within the optimal range of 7.2 to 7.6.
4) Monitor Total Alkalinity: Raising the pH can also affect the total alkalinity (TA) of the pool water. If the TA is too low, it can lead to pH fluctuations. If necessary, adjust the TA before attempting to raise the pH.
5) Take Safety Precautions: When working with pH increasers, always wear appropriate safety gear, including gloves and eye protection, and follow safety guidelines provided by the manufacturer. Store pH increasers in a cool, dry place away from children and pets.
By following these steps and regularly monitoring the pH level of the pool water, you can effectively raise the pH and maintain balanced and comfortable swimming conditions for you and your family.
