Key Facts

• Baking soda, or sodium bicarbonate, is a natural pH and alkalinity buffer, helping to stabilize pool water chemistry, but it is not an algaecide.
• Algae growth in pools is often caused by an imbalance in pH and alkalinity, which can be corrected by adding baking soda, but only in conjunction with an algaecide.
• Maintaining a proper pH level (between 7.2 and 7.8) and total alkalinity level (between 80 and 120 ppm) is crucial for preventing algae growth in pools, and baking soda can help achieve this balance.
• While baking soda can help clear up cloudy water caused by chemical imbalances, it does not directly kill or remove algae; an algaecide or shock treatment is necessary for that purpose.
• According to a study by the Pool & Hot Tub Alliance, using baking soda in combination with chlorine can increase the effectiveness of chlorine in killing algae by up to 30%.

Does Baking Soda Kill Algae in Pools?

Baking soda, or sodium bicarbonate, is not an algaecide and does not directly kill algae. It is used to help raise the pH and alkalinity of pool water, which can indirectly help prevent algae growth by creating an environment where chlorine can work more effectively. When your pool’s pH and alkalinity are balanced, chlorine is more effective at killing algae and other contaminants. However, baking soda alone is not a solution for eliminating an existing algae problem. For that, you’ll need a dedicated algaecide and shock treatment.
