How to Adjust pH in Your Pool

Adjusting the pH level in your pool is a critical aspect of pool maintenance, as it directly affects water quality, swimmer comfort, and the effectiveness of pool chemicals. 

The pH scale ranges from 0 to 14, with 7 being neutral. A pH level below 7 is acidic, while a pH level above 7 is alkaline. 

Here are steps to adjust the pH in your pool:

Test the pH

Test your pool water’s pH with a reliable kit or digital meter before making any adjustments to ensure accuracy. This will give you an accurate baseline reading of the current pH level.

Determine the Target pH

The ideal pH level for pool water typically falls in the range of 7.4 to 7.6. This slightly alkaline range provides a comfortable swimming environment and allows pool chemicals, particularly chlorine, to work most effectively.

Adjust pH Up or Down

Depending on the test results, you may need to adjust the pH either up or down:

  • To raise pH (if it’s too acidic), you can add a pH increaser, which is usually sodium carbonate or soda ash. Follow the manufacturer’s instructions for the correct dosage based on your pool’s size.
  • To lower the pH (if it’s too alkaline), you can use a pH decrease, which is typically muriatic acid or sodium bisulfate. Again, carefully follow the recommended dosage instructions, and add the product to the pool water while the pump and filter system are running.
Circulate the Water

Once pH-adjusting chemicals are added, let the pool water circulate for hours to ensure even distribution and thorough mixing.

Recheck the pH

Re-test the pool water’s pH level to confirm that it has reached the desired range. If necessary, make further adjustments following the same process.
