What Is Normal pH for Pool Alkalinity?

As summer approaches, many eagerly anticipate spending time in their swimming pools. However, while pool maintenance is an obvious necessity, it can be challenging—particularly when it comes to managing chemical balance. 

For example, it’s essential to understand the importance of pH and alkalinity levels and how to lower total alkalinity in the pool because they play a crucial role in maintaining clean, clear, and safe pool water. 

Understanding pH and Alkalinity in Pool Water

The optimal pH range for a pool is 7.2 to 7.8, while the ideal alkalinity should be between 110 and 150 parts per million (PPM). The pH scale measures the acidity or alkalinity of a substance, with 7.0 being neutral.

Pool water should ideally have a pH between 7.2 and 7.8, which is slightly alkaline and ensures the comfort of swimmers. Alkalinity, on the other hand, is a measure of the water’s ability to neutralize acids and resist changes in pH. The recommended total alkalinity level for a swimming pool is typically between eighty and 120 PPM.

pH and alkalinity are both crucial factors in maintaining a clean and safe pool environment. They work together to ensure the effectiveness of sanitizers, prevent damage to pool surfaces and equipment, and provide a comfortable swimming experience for users.

How to Use Baking Soda for Pool Maintenance

Baking soda, also known as sodium bicarbonate, is a versatile and budget-friendly option for maintaining your pool’s water chemistry. It is primarily used to increase alkalinity levels, which in turn helps stabilize pH and ensures a comfortable swimming environment.

To use baking soda, start by testing the alkalinity level of your pool with a pH testing kit. If the level is below eighty PPM, you will need about 1.5 pounds of baking soda per 10,000 gallons of water. Add the baking soda to a bucket of water to dissolve it, and then pour the mixture into the pool water.

What Should be Adjusted First–Alkalinity or pH?

Always adjust the alkalinity level before adjusting the pH level. As mentioned, alkalinity plays a significant role in regulating pH levels. So, if the alkalinity level is balanced, then it is easier to adjust the pH level. Additionally, you may need to learn how to lower alkalinity but raise pH.

Why Is It Important to Maintain Ideal Levels?

Maintaining ideal pH and alkalinity levels is important for several reasons. First, it helps keep your pool water sparkling clean and inviting for swimmers. Second, balanced chemical levels can help extend the lifespan of your pool equipment and reduce maintenance costs. Last but not least, it ensures that your pool is safe and healthy for swimmers by preventing chemical imbalances that can cause skin irritation, eye irritation, and other health problems.

Consistent Pool Water Monitoring

Regular pool water monitoring and testing are vital to maintaining ideal pH and alkalinity levels. Test your pool water at least once a week, or more frequently during heavy usage, after rainstorms, or when making significant chemical adjustments.
