If you've noticed that your swim spa's alkalinity levels are low, you might be wondering what to add as an alkalinity increaser. In this blog post, we'll explore the importance of alkalinity in swim spas, discuss the best products to use for increasing alkalinity, and provide tips on how to maintain optimal levels for your 7-person swim spa.

What is the ideal alkalinity level for a 7-person swim spa?

The ideal alkalinity level for a 7-person swim spa typically ranges between 80 and 120 parts per million (ppm). This range is crucial for maintaining a stable pH level and ensuring the overall health of your swim spa water. Alkalinity acts as a buffer, preventing rapid changes in pH that can occur due to various factors such as rainfall, body oils, and chemicals added to the water.

For a 7-person swim spa, maintaining the proper alkalinity level is particularly important due to the higher bather load. With more people using the spa, there's an increased potential for pH fluctuations caused by body oils, lotions, and other contaminants. The larger water volume in a 7-person swim spa also means that any chemical imbalances can have a more significant impact on water quality.

To maintain the ideal alkalinity level:

1. Test your swim spa water regularly: Use reliable test strips or a liquid test kit to check the alkalinity levels at least once a week, or more frequently if the spa sees heavy use.

2. Adjust gradually: If you need to increase the alkalinity, do so in small increments. Add the alkalinity increaser according to the product instructions, wait for 6-8 hours, and then retest the water.

3. Consider your local water source: The alkalinity of your source water can affect how often you need to adjust the levels in your swim spa. If your local water has naturally low alkalinity, you may need to add an alkalinity increaser more frequently.

4. Balance other chemical levels: Alkalinity is closely related to pH levels. Ensure that you're also maintaining proper pH (typically between 7.2 and 7.8) and sanitizer levels for optimal water balance.

5. Be mindful of bather load: With a 7-person swim spa, keep track of how often it's used and by how many people. Increased use may require more frequent testing and adjustment of alkalinity levels.

6. Use a mineral purifier: Consider using a mineral purifier in conjunction with your regular sanitizer. This can help reduce the amount of chemicals needed and make it easier to maintain stable alkalinity levels.

7. Invest in an automatic chemical feeder: For a large swim spa, an automatic chemical feeder can help maintain consistent alkalinity levels with less manual intervention.

By maintaining the ideal alkalinity level in your 7-person swim spa, you'll ensure a more stable and enjoyable swimming environment, prolong the life of your spa equipment, and reduce the likelihood of water quality issues.

How often should you add alkalinity increaser to a swim spa?

The frequency of adding alkalinity increaser to your swim spa depends on several factors, including usage, water source, and environmental conditions. Generally, you should test your swim spa's alkalinity levels at least once a week and adjust as needed. However, for a 7-person swim spa that sees regular use, you may need to test and adjust more frequently.

Here are some guidelines to help you determine how often to add alkalinity increaser:

1. Regular testing: Test your swim spa water at least 2-3 times per week, especially if it's used frequently. This will help you catch any drops in alkalinity early.

2. After heavy use: If your swim spa has been used by multiple people or for an extended period, test the water immediately afterward. The influx of body oils, sweat, and other contaminants can affect alkalinity levels.

3. Following rainfall: If your swim spa is outdoors, test the water after significant rainfall. Rainwater is typically acidic and can lower both pH and alkalinity levels.

4. Seasonal changes: You may notice that you need to adjust alkalinity more often during certain seasons. For example, in summer when the swim spa is used more frequently, or in areas with frequent rainfall.

5. When opening or closing the swim spa: Always test and adjust alkalinity levels when you're opening your swim spa for the season or preparing it for winter closure.

6. After adding fresh water: Whenever you add fresh water to your swim spa, whether it's a partial or complete refill, test and adjust the alkalinity levels.

7. In response to other chemical additions: If you've recently shocked your swim spa or made significant adjustments to other chemical levels, recheck your alkalinity within 24 hours.

When adding alkalinity increaser:

1. Follow the product instructions carefully. Most alkalinity increasers will provide dosage guidelines based on your current alkalinity level and the volume of your swim spa.

2. Add the product to the swim spa with the jets running to ensure even distribution.

3. Wait at least 6 hours before retesting the water. This gives the chemicals time to fully dissolve and mix throughout the spa.

4. Make incremental adjustments. It's better to slightly under-correct and test again than to overshoot your target alkalinity level.

5. Keep a log of your alkalinity readings and adjustments. This can help you identify patterns and anticipate when you'll need to add more alkalinity increaser.

6. Consider using a stabilized alkalinity increaser product. These are designed to maintain alkalinity levels for longer periods, potentially reducing the frequency of additions.

Remember, maintaining proper alkalinity is crucial for the overall health of your swim spa. It helps prevent equipment corrosion, skin and eye irritation, and makes it easier to maintain other aspects of water chemistry. By staying proactive with testing and adjusting, you'll ensure that your 7-person swim spa remains a safe and enjoyable environment for all users.
