Swimming Pool Tips

By Miami Pool Company

Maintaining the perfect balance in your swimming pool’s water chemistry is essential for ensuring a safe and enjoyable swimming experience. One critical aspect of this balance is the alkalinity level, which helps stabilize the pH and protect your pool from various issues.

Today, our pool experts will walk you through the steps to increase the alkalinity in a swimming pool, ensuring your pool remains a pristine oasis. If you’re in Miami and need professional assistance, remember, Swimming Pools Miami is here to help.

Understanding Pool Alkalinity

Before diving into how to adjust your pool’s alkalinity, it’s important to understand what alkalinity is and why it matters. Alkalinity acts as a buffer for your pool’s pH level, preventing drastic changes that could affect the pool’s environment and the comfort of swimmers.

Certainly, expanding on the importance of maintaining alkalinity in a pool can offer readers deeper insights into effective pool management. Here’s a more detailed exploration of these points:

Why is Maintaining Alkalinity Important?

Properly managing the alkalinity levels in a swimming pool is not just a routine aspect of maintenance; it’s a foundational practice that affects nearly every aspect of your pool’s health and usability.

Alkalinity, often overshadowed by the more commonly discussed pH levels, actually plays a pivotal role in stabilizing those very pH values, ensuring they remain within a safe range for both the pool’s physical components and its users.

But why exactly is this balance so critical? Let’s dive deeper into the reasons why maintaining the correct alkalinity level is essential for the longevity of your pool equipment, the effectiveness of your pool’s sanitation efforts, and the overall comfort of your swimming pool.

Protecting Pool Equipment from Corrosion

Maintaining the correct alkalinity level in your pool water is not just about ensuring a pleasant swim; it’s also about safeguarding your investment.

Alkalinity acts as a critical buffer for the pool’s pH levels. When alkalinity is too low, the water becomes acidic, posing a risk of corrosion to pool surfaces and equipment. This corrosion can lead to significant damage over time, affecting ladders, liners, and even the pool pump and filtration system.

By keeping alkalinity within the ideal range, you extend the life of these components, ensuring they continue to function efficiently and saving you from costly repairs or replacements.

Ensuring the Effectiveness of Chlorine

Chlorine is the most common chemical used to sanitize pool water, killing bacteria and algae to keep the water clean and safe for swimming. However, chlorine’s effectiveness is heavily dependent on the pool water’s pH balance, which is stabilized by the alkalinity level.

When alkalinity is too low, it can cause the pH level to fluctuate wildly, reducing the effectiveness of chlorine and making it harder to maintain a sanitized pool.

The right alkalinity level stabilizes pH values, enhancing chlorine’s ability to perform its disinfectant duties. This balance ensures your pool remains a safe, enjoyable environment for everyone.

Providing a Comfortable Swimming Experience

One of the most noticeable benefits of maintaining proper alkalinity levels is the comfort it offers swimmers. Incorrect alkalinity and pH levels can lead to eye and skin irritation, making the swimming experience unpleasant.

High acidity, for instance, can cause swimmers to experience itchy skin and red, irritated eyes. On the other hand, water that’s too alkaline can lead to feelings of sliminess on the skin and scale formation on the pool surfaces and in the water.

By keeping alkalinity levels within the recommended range, you ensure the water remains gentle on the skin and eyes, enhancing the overall swimming experience.

How to Raise The Alkalinity In A Pool: Step-by-Step Guide

Increasing the alkalinity in a swimming pool is a straightforward process, but it requires precision and care. Follow these steps to adjust your pool’s alkalinity safely:

Total Time: 4 hours

Test the Water

Before making any adjustments, test your pool water to determine the current alkalinity level. The ideal range is between 80-120 ppm (parts per million).

Calculate the Amount of Alkalinity Increaser Needed

Based on the test results, calculate how much alkalinity increaser (usually sodium bicarbonate) you need to add to reach the ideal range.

Add the Alkalinity Increaser To Your Pool

Distribute the increaser evenly around the pool’s perimeter and near the return jets for optimal dispersion.

Re-test and Adjust

Wait for the chemicals to circulate, then re-test the water. If the alkalinity is still below the ideal range, repeat the process.

Additional Pool Maintenance Tips

Beyond your pool’s alkalinity, comprehensive pool care encompasses several facets to ensure your pool is always inviting and safe.

Regular Cleaning

Commit to a regular cleaning schedule, including skimming, vacuuming, and brushing the pool surfaces to prevent algae buildup and maintain clear water.

Filter Maintenance

Keep your pool’s filter system in optimal condition by regular cleaning and timely replacement of filter media, ensuring efficient operation and water clarity.

Shock Treatment

Periodically perform shock treatments to eliminate bacteria, algae, and other contaminants, maintaining a hygienic swimming environment.

Water Level Management

Monitor and maintain the appropriate water level, especially after heavy rainfall or extensive usage, to ensure efficient system operation.

FAQs: Everything You Need to Know About Increasing Pool Alkalinity

How often should I test my pool’s alkalinity?

Regular testing is key to maintaining the perfect water balance. Test your pool’s alkalinity weekly.

Can I swim in the pool after adding an alkalinity increaser?

It’s best to wait at least 20 minutes after adding chemicals before swimming, to allow them to fully disperse.

What should I do if I accidentally raise the alkalinity too much?

If the alkalinity exceeds the recommended level, you can lower it by adding muriatic acid or sodium bisulfate, following a similar process but in reverse.

Can high alkalinity damage my pool liner or cause stains?

Yes, excessively high alkalinity can lead to scale formation, which not only makes the pool water cloudy but can also deposit on surfaces, including liners, leading to staining and potential damage. Keeping alkalinity in the recommended range helps protect against these issues.

How does pool size affect alkalinity adjustment?

Pool size directly affects the amount of chemicals needed to adjust alkalinity. Larger pools require more alkalinity increaser to achieve the same change in ppm (parts per million) as smaller pools. Always calculate the required amount based on your pool’s volume before making adjustments.

How quickly can pool alkalinity levels change?

Pool alkalinity levels can fluctuate due to various factors, including heavy rainfall, large numbers of swimmers, and the addition of pool chemicals. Regular testing, at least once a week, is recommended to monitor these changes and adjust as necessary to maintain ideal levels.


Learning how to raise the alkalinity in a pool is an essential part of maintaining a healthy, enjoyable swimming environment. By following the steps outlined in this guide and keeping up with regular maintenance, you can ensure your pool remains a welcoming oasis for all to enjoy.
