Raise pH level in swimming pool?

1. Add baking soda (sodium bicarbonate). Baking soda is one of the most effective and inexpensive ways to increase pH levels in a pool. It's also safe and easy to use. Simply add baking soda directly to the pool water and stir until dissolved. You'll need about 1.5 pounds of baking soda for every 10,000 gallons of pool water.

2. Use a commercial pH increaser. There are a number of commercial pH increasers available at pool stores. These products typically come in granular or liquid form, and they work by adding a base to the pool water, which raises the pH level. Follow the directions on the package for how to use a commercial pH increaser.

3. Add soda ash (sodium carbonate). Soda ash is a good option if the pH level in your pool is extremely low. It's more powerful than baking soda and should only be used as a last resort. Add soda ash directly to the pool water and stir until dissolved. You'll need about 1 pound of soda ash for every 10,000 gallons of pool water.

4. Circulate the pool water. Once you've added the pH increaser, circulate the pool water for several hours to ensure that it's evenly distributed. You can do this by running the pump or using a pool vacuum.

5. Test the pH level. After you've circulated the pool water, test the pH level again to make sure it's within the ideal range of 7.2 to 7.8. You can use a test kit or a pool water test strip.

It's important to note that raising the pH level in your pool too much can be dangerous. If the pH level is too high, it can irritate your skin and eyes, and it can also damage the pool equipment. Be sure to follow the directions on the pH increaser package and test the pH level regularly to avoid this.
