5 Best Pool Chemicals for Low Alkalinity

If you own a pool, you know the importance of keeping it clean and balanced. One of the most important factors in maintaining a healthy pool is proper water chemistry. The pH level and alkalinity are crucial factors in ensuring that the water remains safe and clear.

If you have low alkalinity in your pool, it can lead to a host of problems, such as corrosion, staining, and difficulty in maintaining chlorine levels. In this article, we will discuss the best pool chemicals for low alkalinity, so you can keep your pool clean and healthy.

Best Pool Chemicals for Low Alkalinity

1. Sodium Bicarbonate

Sodium bicarbonate, or baking soda, is a commonly used pool chemical to increase alkalinity. It’s affordable and easy to use. To increase alkalinity, add 1.5 pounds of sodium bicarbonate per 10,000 gallons of water.

It’s important to add this chemical slowly and in small amounts, so as not to raise the pH level too quickly.

2. Sodium Carbonate

Sodium carbonate, also known as soda ash, is another effective pool chemical for increasing alkalinity. It’s more potent than sodium bicarbonate, so it’s important to use it in small amounts.

To increase alkalinity, add 1.25 pounds of sodium carbonate per 10,000 gallons of water.

3. Sodium Sesquicarbonate

Sodium sesquicarbonate is a combination of sodium carbonate and sodium bicarbonate. It’s a great option for those who need to raise both alkalinity and pH levels.

To increase alkalinity, add 1.5 pounds of sodium sesquicarbonate per 10,000 gallons of water.

4. Alkalinity Increaser

An alkalinity increaser is a pool chemical specifically designed to increase alkalinity. It’s a combination of sodium bicarbonate and sodium carbonate.

It’s easy to use and highly effective. To increase alkalinity, follow the instructions on the package.

5. Calcium Carbonate

Calcium carbonate is another effective pool chemical for increasing alkalinity. It’s also known as limestone. To increase alkalinity, add 1.25 pounds of calcium carbonate per 10,000 gallons of water.

Understanding Alkalinity

Before we dive into the best pool chemicals for low alkalinity, it’s important to understand what alkalinity is and why it’s important. Alkalinity is a measure of the water’s ability to neutralize acids.

In other words, it’s a measure of the water’s buffering capacity. If the alkalinity is too low, the water can become too acidic, which can lead to corrosion of the pool’s surfaces, equipment, and plumbing.

Symptoms of Low Alkalinity

There are several symptoms that can indicate low alkalinity in your pool. These include:

• Cloudy water
• Staining or discoloration of the pool’s surfaces
• Corrosion of metal pool equipment
• Difficulty in maintaining chlorine levels
• Irritation to the eyes and skin

If you notice any of these symptoms, it’s important to test the alkalinity of your pool water.

Testing Alkalinity

The first step in treating low alkalinity is to test the water.

You can do this using a pool testing kit or by taking a sample of your pool water to a local pool supply store for testing.

The ideal range for alkalinity is between 80–120 parts per million (ppm). If your test results indicate that the alkalinity is below this range, it’s time to take action.

Conclusion

Maintaining proper water chemistry is essential for keeping your pool clean and healthy. If you have low alkalinity, it’s important to take action to avoid corrosion and staining of your pool’s surfaces, equipment, and plumbing.

By understanding the symptoms of low alkalinity and testing your pool water regularly, you can catch the problem early and treat it effectively, using the best pool chemicals for low alkalinity.

Remember to add pool chemicals slowly and in small amounts, so you don’t shock the water or raise the pH level too quickly.

Follow the instructions on the package and make sure to retest the water after adding chemicals to ensure that you have reached the desired alkalinity level.

By using the best pool chemicals for low alkalinity, you can ensure that your pool water remains balanced and safe for swimming. Don’t let low alkalinity ruin your pool experience – take action today to keep your pool clean, clear, and healthy.
