How much baking soda do you need to increase pH in a 25 round 4ft deep pool?

The amount of baking soda needed to increase the pH in a 25-round, 4-foot-deep pool will depend on several factors, including the current pH level of the water, the desired pH level, and the alkalinity of the water.

To accurately determine the amount of baking soda required, it is recommended to test the pH and alkalinity levels of the pool water using a reliable test kit. Once you have these values, you can use a pool chemical calculator or consult with a pool maintenance expert to determine the appropriate dosage of baking soda.

In general, raising the pH of pool water by 0.1 units may require approximately 1.5 pounds of baking soda per 10,000 gallons of water. However, this is just an approximate value and may vary depending on the specific conditions of your pool.

It's important to follow the instructions provided on the baking soda packaging and to make gradual adjustments to the pH level to avoid over-correction. Additionally, it's recommended to monitor the pH and alkalinity levels regularly and make adjustments as needed to maintain the ideal pool water chemistry.
