What household item could use to raise pH in pool?

Baking soda (sodium bicarbonate) is a common household item that can be used to raise the pH of your swimming pool. When added to water, baking soda releases sodium and bicarbonate ions, which can help to increase the alkalinity and pH of the water. To use baking soda to raise the pH of your pool, add 1-2 pounds of baking soda per 10,000 gallons of water. If needed, you can add more baking soda in increments of 1 pound per 10,000 gallons of water until the desired pH level is reached.
