How to Raise pH in Pool: A Comprehensive Guide

Understanding the pH level of your swimming pool is essential for keeping it healthy and making sure that everyone who uses it has a safe, happy time. We’ll talk about how to increase a pool’s pH in this blog post.

Understanding pH in Your Pool

Let’s take a moment to define pH and discuss its significance before getting into the intricacies of raising the pH in a pool.

pH is a measurement that tells us how acidic or alkaline (basic) a solution is. The scale ranges from 0 to 14. Below 7 is acidic, above 7 is alkaline, and pH 7 is regarded as neutral. The optimal pH for a swimming pool is slightly alkaline, between 7.4 and 7.6.

If the pH of your pool water is too low (acidic), it can lead to problems like skin and eye irritation for swimmers, corrosion of pool equipment, and decreased chlorine effectiveness. Therefore, knowing how to raise pH in your pool is crucial.

How to Raise pH in Pool

Let’s look at the actions you can take to boost the pH in your pool now that we have a better understanding of the significance of pH in a swimming pool.

Using Soda Ash or Sodium Bicarbonate

  • Test the pH: The first step is to use a pool water test kit to determine the pH level of the water in your pool. This will help you determine exactly how much pH adjustment is required.
  • Calculate the required amount: Based on your pool size and current pH level, calculate how much soda ash or sodium bicarbonate you need. There are several different internet calculators that can help with this.
  • Add soda ash or sodium bicarbonate to the pool by dissolving the necessary amount in a pail of water beforehand. It’s best to add the mixture to the deepest part of the pool and while the pump is running to help distribute it evenly.
  • Retest the pH: Take a few hours to pass before doing so. Repeat the procedure until you reach the required pH level if it’s still too low.

Using a pH Increaser


Another option for raising the pH in your pool is to use a commercial pH increaser. These are readily available at pool supply stores and work in a similar way to soda ash or sodium bicarbonate. Always adhere to the manufacturer’s directions since they may differ based on the product.

How to Raise the pH Level in Your Pool Water Naturally

Perhaps you’re wondering how to raise the pH level in your pool water naturally. While there are fewer options, it is indeed possible.

Using Baking Soda


Baking soda, one of the most widely used household goods, may also be used to increase the pH of a pool. In essence, sodium bicarbonate, which we previously spoke about, is what baking soda is.

  • Determine how much baking soda you need: This will be based on your pool’s volume and the current pH level.
  • Add baking soda: While the pump is running, dissolve the necessary amount of baking soda in a bucket of water, then add it to your pool.
  • Measure the pH: The pH level should be checked after a few hours.
  • Up until the target pH level is achieved, repeat the procedure as necessary.

FAQs on How to Raise pH in Pool

How can I add pH to my pool?

You can add pH to your pool by using substances such as soda ash, sodium bicarbonate, a commercial pH increaser, or even household baking soda. While the pump is running, dissolve the required quantity in a bucket of water and add it to the pool.

What happens if pH is too low in pool?

The water in your pool is too acidic if the pH is too low. This can cause swimmers’ skin and eyes to itch, pool equipment to corrode, and chlorine’s ability to effectively keep the water clean and bacteria-free to decline.

How can I raise the pH level in my water naturally?

You can raise the pH level in your pool water naturally by using baking soda. Determine the required quantity based on the pH level in your pool right now and its volume, dissolve it in water, and then add the solution to your pool.

In conclusion, understanding how to raise pH in your pool is crucial for maintaining a safe and enjoyable swimming environment. You can make sure that your pool is healthy and balanced for everyone to enjoy by routinely evaluating the pH level and making any necessary corrections.

Importance of Regular pH Testing and Monitoring

Regular testing and monitoring are essential aspects of knowing how to raise pH in your pool and maintain a healthy swimming environment. pH fluctuates due to various factors including swimmer load, weather conditions, and the addition of other chemicals. Therefore, pool owners should test their pool’s pH at least once a week. More frequent testing may be necessary during periods of heavy use or significant weather changes.

Keeping a regular log of your pool’s pH levels can help identify patterns and anticipate necessary adjustments. In addition to pH, also check other factors like total alkalinity and chlorine levels, as these can affect and be affected by pH.

Dealing with Pool Alkalinity

While we focus on how to raise pH in your pool, it’s equally important to remember that pH and alkalinity are closely linked. Total alkalinity measures the water’s ability to neutralize acid. If the total alkalinity is too low, your pool’s pH levels can swing in and out of balance quickly.

If your pool’s alkalinity is low, you’ll need to raise it before adjusting pH. To improve total alkalinity, sodium bicarbonate can also be utilised.
If you see that your pH and alkalinity levels are consistently out of balance, this may be a symptom of a more serious problem, so you should probably consult a pool expert.

Precautionary Measures When Adjusting Pool pH

As with any chemical, it’s crucial to handle substances used to adjust pH with care. Always use gloves and eye protection when handling chemicals. It’s also wise to add chemicals to water, not water to chemicals, to prevent violent reactions.

Moreover, never mix different chemicals. Mixing can result in dangerous reactions. Add each chemical separately to the pool, allowing ample time for one to fully incorporate before adding another.

Last but not least, remember to keep any pool chemicals out of children’s reach and in a dry, cool, well-ventilated place that is out of direct sunlight.

In Summary: Maintaining and Raising pH in Pool

Knowing how to raise pH in your pool is key to maintaining an optimal swimming environment. Regular testing, monitoring, and adjustment as needed will ensure the health and longevity of your pool and the safety and comfort of swimmers.

Whether you’re using soda ash, sodium bicarbonate, a commercial pH increaser, or a natural method like baking soda, raising the pH of your pool requires careful calculation, consideration, and safety precautions.

And remember, while pH is important, it’s not the only parameter to monitor in your pool. Total alkalinity and chlorine levels also play a crucial role in maintaining your pool’s balance. By maintaining this balance, you can ensure a clean, clear pool that will be enjoyed by all.
