Beyond its well-known roles as a common cleaner and leavening ingredient in baking, baking soda offers a wide range of practical uses in everyday life. From its use in cooking to baking to odor elimination, baking soda is a safe, effective, and eco-friendly option.

Adding a bit of baking soda to your pool can improve the water clarity, decrease algae buildup, reduce corrosion, stabilize the pH, and more. Start by testing the water’s pH levels and alkalinity.

Allow it to circulate for a few hours and then retest the water and adjust the quantities if necessary.
