Raising pH Levels in Your Swimming Pool: A Comprehensive Guide

Raising pH Levels in Your Swimming Pool_ A Comprehensive Guide

Both the safety of swimmers and the durability of pool equipment depend on maintaining the right pH level in a pool. A swimming pool should have a pH between 7.2 and 7.8. It is necessary to restore the pH level to the ideal range because a variety of factors can cause it to decrease.

In this article, we will discuss everything you need to know about pH levels, common causes of low pH, and various methods for raising pH levels in your swimming pool.

Understanding pH Levels

It’s crucial to first comprehend what pH levels are and how they are calculated. The term pH, which stands for “potential of hydrogen,” is used to describe how acidic or basic a solution is. On a scale of 0 to 14, where 0 is the most acidic, 7 is neutral, and 14 is the most basic, pH levels are measured.

Maintaining a pH level in a swimming pool between 7.2 and 7.8 is crucial because anything outside of this range can harm swimmers’ health and pool equipment. Low pH levels in a pool can lead to problems like dry skin, itchy eyes, and discoloration of the pool liners and other pool equipment.

On the other hand, high pH levels can result in corrosion, scaling, and cloudiness. To make sure that the pH level of your swimming pool stays within the ideal range, it is crucial to regularly check and adjust it.

Common Causes of Low pH Levels

Rainwater is one of the most typical sources of low pH levels in swimming pools. Since rainwater is naturally acidic, it may lower the pH of the pool when it enters.

Low pH levels in a swimming pool can also be brought on by poor-quality pool chemicals and excessive chlorine levels. These elements can result in acidic water, which harms pool liners and equipment and discolors surfaces.

Raising pH Levels

Fortunately, increasing the pH levels in a pool is not too difficult. Adding baking soda, soda ash, and pH increasers are a few techniques that can be used to raise pH levels. It’s important to adhere to the directions on the package when adding these chemicals and avoid adding too much at once.

An inexpensive household item called baking soda can be used to increase the pH of a pool. It is an organic alkaline substance that can assist in quickly boosting pH levels. To raise the pH level by 0.2, merely add 1 pound of baking soda per 10,000 gallons of water.

Another chemical that can be used to raise the pH of a pool is soda ash. It can be added directly to the pool and is a stronger chemical than baking soda. To increase the pH by 0.2, it is advised to use 1 pound of soda ash per 10,000 gallons of water.

To increase the pH of swimming pools, pH increasers were created. These chemicals can be added directly to the pool and are simple to use. To avoid overcorrecting the pH level when using these chemicals, it’s crucial to adhere to the manufacturer’s instructions.

Monitoring and Maintaining pH Levels

It’s crucial to regularly check and adjust the pH level of your swimming pool to make sure it stays within the ideal range. You can do this by using a pH test kit or by taking a sample of your water to a nearby pool supply shop. At least once per week should be set aside for pH testing.

It’s critical to adjust chlorine levels, water flow, and frequently add pH-balancing chemicals to maintain the right pH level. For ideal pH levels, the chlorine concentration in the pool should be between 1 and 3 parts per million (ppm). The pH balance is maintained in part by water flow. You can lessen the amount of acid that enters the pool and support the maintenance of a stable pH level by adjusting the water flow.

It’s crucial to avoid over-correcting pH levels because doing so could harm swimmers and pool equipment. Furthermore, it’s crucial to avoid using too much of any one chemical. Chemical overuse can result in pH level fluctuations and other issues.


The safety of swimmers and the longevity of pool equipment both depend on maintaining the proper pH level in a swimming pool. You can make sure that everyone can use your swimming pool safely and enjoyably by learning about pH levels, typical causes of low pH levels, and different methods for raising pH levels.

Keep in mind not to overcorrect pH levels and to frequently check and adjust the pH level as well as chlorine levels. Your swimming pool will give you and your loved ones years of enjoyment with proper care and maintenance.
