What Does Baking Soda Do to a Pool?
Most people know baking soda as a staple ingredient in their kitchens, perfect for baking cookies and cakes. But did you know this versatile household item can also work wonders in your swimming pool? That’s right! Baking soda, or sodium bicarbonate, isn’t just for your pantry—it’s a secret weapon for pool maintenance.
In this article, we’ll explore the benefits of using sodium bicarbonate in your pool, from balancing pH levels to preventing algae growth. Whether you’re a seasoned pool owner or new to the game, understanding how baking soda can improve your pool’s health and clarity will make a big difference in your maintenance routine. Let’s dive in and uncover what sodium bicarbonate can do for your pool!
Understanding Pool Chemistry
First off, let’s talk a little bit about pool chemistry. You might think maintaining a pool is just about keeping the water clean, but there’s a bit more to it. The chemical balance of your pool water is crucial for both the health of the swimmers and the longevity of the pool itself. One of the key elements of this balance is pH level, which measures how acidic or basic the water is.
pH Levels and Why They Matter
When the pH level of your pool is off, it can lead to a host of problems. If the water is too acidic (low pH), it can cause skin and eye irritation, corrosion of pool equipment, and etching of the pool surface. On the flip side, if the water is too basic (high pH), it can lead to cloudy water, scaling on pool surfaces and plumbing, and reduced effectiveness of chlorine.
Enter Baking Soda
Also known as sodium bicarbonate, baking soda is a common ingredient in baking and likely sits in your pantry right now. It’s so versatile, many people also use it as a natural alternative for household cleaning and deodorizing products. But did you know it’s an essential part of pool maintenance? Baking soda is truly a pool owner’s best friend!
Raising Alkalinity with Baking Soda
One of the primary uses of baking soda in a pool is to raise the total alkalinity. Total alkalinity is a measure of the water’s ability to resist changes in pH. When your pool’s alkalinity is within the ideal range (80-120 ppm), it acts as a buffer for the pH, preventing sudden swings that can throw everything out of balance.
To raise the alkalinity, you’ll want to add sodium bicarbonate to your pool. The general rule of thumb is to add 1.5 pounds of baking soda per 10,000 gallons of water to raise the alkalinity by 10 ppm. Always add it in small amounts, and spread it evenly across the surface of the pool. Remember to test the water after a few hours and adjust as necessary.
Stabilizing pH Levels
But wait, there’s more! Baking soda not only helps with alkalinity but also plays a role in stabilizing pH levels. When you add baking soda to your pool, it helps to bring the pH level into the ideal range (7.2-7.6). This dual-action makes it a cost-effective and efficient solution for maintaining your pool’s chemical balance.
Preventing Algae Growth
Nobody likes a green, slimy pool, right? Another benefit of using baking soda is that it can help prevent algae growth. Algae thrives in environments where the pH is not properly balanced. By using sodium bicarbonate to maintain a stable pH and alkalinity, you create a less hospitable environment for algae, keeping your pool crystal clear and inviting.
How to Add Baking Soda to Your Pool
Now, let’s get practical. How do you add baking soda to your pool? It’s super simple. Here’s a step-by-step guide:
- Test Your Water: Always start by testing your pool water. You need to know your current pH and alkalinity levels to determine how much baking soda to add.
- Calculate the Amount: Based on your test results, calculate how much baking soda you need. Remember the rule: 1.5 pounds per 10,000 gallons of water raises alkalinity by 10 ppm.
- Add Sodium Bicarbonate: Spread the baking soda evenly across the surface of the pool. It’s best to do this when the pool pump is running to help it dissolve and distribute evenly.
- Wait and Test Again: Give it a few hours, then test the water again. If needed, add more baking soda in small amounts until you reach the desired levels.

Safety First
While baking soda is generally safe to use, it’s always important to handle it properly. Avoid inhaling the powder, and if you have sensitive skin, consider wearing gloves. Keep the baking soda stored in a dry, cool place away from children and pets.
The Cost-Effective Solution
One of the best things about using baking soda is its cost-effectiveness. Pool chemicals can be expensive, but baking soda is an affordable alternative that you can find at any grocery store. Plus, it’s versatile! You can use it for cleaning around the house too.
Other Benefits of Baking Soda in Your Pool
You might be wondering if there are any other benefits of using sodium bicarbonate in your pool. The answer is yes! Here are a few more reasons why baking soda is a great addition to your pool maintenance routine:
- Improved Water Clarity: By stabilizing the pH and alkalinity, baking soda helps keep your pool water clear and sparkling. No one likes swimming in murky water, and baking soda can help you avoid that.
- Enhanced Comfort: Properly balanced water feels better on your skin and eyes. Baking soda helps achieve that perfect balance, making your swimming experience more enjoyable.
- Prolonged Equipment Life: High acidity can corrode your pool equipment over time. By using baking soda to maintain the right pH levels, you can protect your investment and extend the life of your pool pump, filter, and other equipment.
Conclusion
So, to sum it up, what does sodium bicarbonate do to a pool? It raises total alkalinity, stabilizes pH levels, and helps prevent algae growth. It’s a budget-friendly, readily available solution that can make maintaining your pool a breeze.
Now that you know the secrets of baking soda, you’ll be well on your way to enjoying a perfectly balanced, sparkling clean pool all summer long!
FAQs – Frequently Asked Questions
Yes, baking soda can help treat cloudy pool water. Cloudiness is often due to unbalanced pH and alkalinity levels. By adding baking soda, you can stabilize these levels, which can help clear up the water. However, it’s important to test your water first to determine if baking soda is the appropriate treatment.
Yes, baking soda can help reduce pool odors. Unbalanced pH levels can lead to unpleasant smells in your pool. By using sodium bicarbonate to stabilize the pH, you can minimize these odors, making your pool more pleasant to use.
Baking soda can be effective in removing light pool stains, especially those caused by organic materials. You can use a baking soda paste (sodium bicarbonate mixed with a little water) to scrub away stains on pool tiles and surfaces. For tougher stains, you might need a specialized pool cleaner.
While baking soda helps stabilize pH and alkalinity, it does not directly affect chlorine levels. However, balanced pH levels can enhance the effectiveness of chlorine, ensuring that it works efficiently to sanitize your pool.
Yes, it is generally safe to swim immediately after adding sodium bicarbonate to your pool. Baking soda is a mild substance and does not create harmful chemical reactions. Just ensure it’s evenly distributed and dissolved by running the pool pump for a while before swimming.
