How do you lower the Ph in inground swimming pool?

1. Test the pool water: Use a pool water test kit to measure the current pH level of your pool water. The ideal pH range for swimming pools is between 7.2 and 7.8.

2. Calculate the amount of pH decreaser needed: Determine how much pH decreaser (sodium bisulfate or muriatic acid) you need to add to lower the pH. Use a pool chemical calculator or follow the instructions on the product label to determine the correct amount based on the pool volume and current pH level.

3. Dissolve the pH decreaser: Always add chemicals to the pool slowly and with caution. Dissolve the pH decreaser in a bucket of pool water before adding it to the pool to prevent any splashes.

4. Add the pH decreaser to the pool: Broadcast the dissolved pH decreaser evenly over the surface of the pool water while the pump is running to ensure proper circulation.

5. Circulate the pool water: Run the pool pump for several hours after adding the pH decreaser to ensure the chemical is distributed throughout the water and the pH level starts to adjust.

6. Retest the pool water: After several hours, test the pH level of the pool water again to ensure it is within the desired range.

7. Adjust as needed: If necessary, repeat steps 2-6 until the desired pH level is achieved.

8. Monitor and maintain the pH level: Regularly monitor the pH level of your swimming pool and make adjustments as needed to keep it within the recommended range.

Remember to handle and use pool chemicals safely, following the instructions on the product labels and ensuring proper ventilation. If you have any doubts or concerns about adjusting the pH level of your pool, it's best to consult with a pool maintenance professional.
