If your pool is equipped with fountains, waterfalls, or other water features, make sure to run them regularly to increase aeration. The movement of water and exposure to the air will facilitate the release of carbon dioxide and raise alkalinity levels. Adjust the flow and intensity of the water features to ensure adequate aeration throughout the pool.
Using an Aerator
If your pool does not have built-in water features, you can use a pool aerator. These devices are designed to agitate the water’s surface and enhance aeration. Place the aerator in the pool and let it run for several hours or as recommended by the manufacturer. This will help release carbon dioxide and increase alkalinity.
Limit Acidic Chemical Usage
Excessive use of acidic chemicals, such as muriatic acid or pH decreasers, can lower the pool’s alkalinity. To maintain proper alkalinity levels, limit the use of these chemicals and opt for alkaline alternatives whenever possible.
Minimizing the use of acidic chemicals will help prevent a decrease in alkalinity. Choose alkaline alternatives whenever feasible.
Alternative Pool Chemicals
When adjusting pH levels or treating other water balance issues, consider using alkaline alternatives. For example, instead of using muriatic acid to lower pH, you can use sodium bisulfate, which has a less significant impact on alkalinity. Similarly, opt for alkaline-based products for other pool maintenance tasks to minimize the potential reduction in alkalinity.
Balancing Chemicals with Alkalinity in Mind
When adding chemicals to your pool, be mindful of their impact on alkalinity. Understand the chemical interactions and their effects on water balance. Consider adjusting the alkalinity level first before adding other chemicals to maintain optimal water balance.
