How to Lower the Alkalinity in a Swimming Pool


Posted December 12, 2024 by cutters_pools

Alkalinity refers to the water’s ability to resist changes in pH. Essentially, it acts as a buffer to prevent drastic shifts in acidity or alkalinity.

 
Austin, Taxes – Maintaining a swimming pool can be a rewarding but challenging task for homeowners. One of the most crucial aspects of pool care is keeping the water balanced, and this includes managing the alkalinity levels. If you’ve noticed that the pH levels of your pool water are off, and the water is cloudy or doesn’t seem to be properly sanitized, it might be time to lower the alkalinity in your swimming pool.

In this guide, we’ll walk you through the process of lowering pool alkalinity, the signs of high alkalinity, and the steps you can take to restore balance, ensuring that your pool remains clean, clear, and safe for swimming.

Understanding Pool Alkalinity: Why It Matters

Alkalinity refers to the water’s ability to resist changes in pH. Essentially, it acts as a buffer to prevent drastic shifts in acidity or alkalinity. If your pool has too high of an alkalinity level, it can cause several issues:
Difficulty in adjusting pH: High alkalinity can make it harder to adjust the pH of your pool. Even after adding pH reducers, the water may not stabilize.

Cloudy Water: Elevated alkalinity levels can lead to cloudy or murky water, which is unappealing and may indicate a chemical imbalance.

Scaling: High alkalinity can lead to calcium buildup on your pool’s surface, resulting in scale deposits and stains.

Reduced Effectiveness of Chlorine: When the alkalinity is too high, chlorine may not work as efficiently, affecting your pool’s sanitation.

Signs Your Pool’s Alkalinity Is Too High

Before diving into solutions, it’s important to confirm whether your pool’s alkalinity is indeed high. Pool owners can use a simple test kit to measure alkalinity levels. Here’s what you should look for:

Alkalinity Levels Above 150 ppm: The ideal alkalinity range for pool water is between 80 and 120 ppm (parts per million). If your alkalinity test reads higher than 150 ppm, it’s time to take action.

pH Imbalance: A high alkalinity level can cause the pool’s pH level to also become elevated. If your pH level is consistently higher than 7.8, this could be a sign that your alkalinity needs attention.

Cloudy Water: As mentioned earlier, high alkalinity may cause cloudy or hazy water, signaling a chemical imbalance.

Poor Sanitizer Performance: If your chlorine isn’t working effectively and the water doesn’t seem to stay clean, high alkalinity could be the culprit.

How to Lower the Alkalinity in a Swimming Pool: Step-by-Step Instructions

Now that you know the signs of high alkalinity, it’s time to take action. Lowering the alkalinity in a swimming pool can be achieved through the following steps.

1. Test Your Water
The first step in addressing any chemical imbalance is testing your pool water. Use a reliable pool test kit to measure both pH and alkalinity levels. This will give you a clear understanding of how much intervention is needed.

2. Add Muriatic Acid or Sodium Bisulfate
To lower the alkalinity in a swimming pool, you’ll need to use an acid. The most commonly used chemicals are muriatic acid or sodium bisulfate (dry acid). Muriatic acid is more powerful, but it should be handled with caution as it is corrosive. Sodium bisulfate is safer for many pool owners, but it may take more time to work.

For Muriatic Acid: Add about 1 quart of muriatic acid for every 10,000 gallons of water for every 10 ppm reduction in alkalinity. Always add the acid to the water (never the reverse) to avoid splashing. Use a pool brush to distribute the acid evenly in the pool.

For Sodium Bisulfate: Follow the manufacturer’s instructions on the packaging, typically adding 1 pound of sodium bisulfate per 10,000 gallons to lower alkalinity by approximately 10 ppm.

3. Circulate the Water
Once the acid is added to the pool, it’s essential to circulate the water thoroughly. Run the pool pump for at least 4-6 hours after adding the acid to ensure the chemical is evenly distributed. This will help ensure that the alkalinity begins to lower effectively.

4. Test and Retest
After the circulation period, test your pool water again. You may need to repeat the process several times to achieve the desired alkalinity level. It’s crucial not to make large adjustments in a single treatment to prevent over-correction. Make small, gradual changes and test frequently to avoid creating other imbalances.

5. Maintain Proper pH Levels
As you lower the alkalinity in your swimming pool, remember that pH levels can also drop. The pH should ideally remain between 7.2 and 7.6. If the pH dips too low after adding acid, use a pH increaser (soda ash or sodium carbonate) to bring the pH back into balance.

6. Regular Maintenance
Once your pool’s alkalinity is properly adjusted, maintaining the correct balance is key to preventing future issues. Regular testing and proper maintenance, including cleaning your pool filter, keeping debris out of the pool, and balancing chemicals, are vital to sustaining water clarity and quality.

Additional Tips to Prevent High Alkalinity in the Future
Regular Water Testing: Test your pool water at least once a week to monitor alkalinity levels and adjust before they reach problematic levels.

Use Pool Covers: Pool covers can prevent debris from entering the pool, which can affect chemical balance.
Consider the Water Source: If you’re filling your pool with well water, it may have a naturally high alkalinity level. In such cases, using a pre-filter before adding water to the pool can help reduce this issue.

Conclusion

Knowing how to lower the alkalinity in a swimming pool is essential for maintaining clear, clean, and balanced water. By following these simple steps and staying on top of regular water testing, pool owners can ensure that their pool stays in excellent condition, with proper sanitation and optimal water chemistry.
