How to adjust swimming pool pH without chemicals?

Adjusting swimming pool pH without chemicals can be challenging but is possible with certain natural methods:
1) Pool Cover: Keeping the pool covered when not in use can help prevent pH fluctuations caused by exposure to sunlight and atmospheric carbon dioxide. A pool cover reduces the rate of evaporation and minimizes the entry of debris, helping to maintain water balance more effectively.
2) Aeration: Increasing the level of dissolved oxygen in the pool water through aeration can help raise pH naturally. This can be achieved by running water features like fountains or waterfalls, or by using a pool aerator. Aeration promotes the outgassing of carbon dioxide, which in turn raises the pH of the water.
3) Carbon Dioxide Off-Gassing: Allowing carbon dioxide to escape from the pool water naturally raises the pH. This can be achieved by keeping the pool uncovered during the day when the sun is out. Sunlight triggers photosynthesis in algae and aquatic plants, which consume carbon dioxide and release oxygen, leading to natural pH elevation.
4) Use of Baking Soda: While technically a chemical (sodium bicarbonate), baking soda is considered a safer and more natural alternative to traditional pool chemicals. Adding baking soda to the pool water can raise pH levels without introducing harsh chemicals. However, it's essential to use baking soda sparingly and test the water regularly to avoid overcorrection.
5) Borax: Borax, also known as sodium borate, is another natural substance that can be used to raise pH levels in a swimming pool. It acts similarly to baking soda but is less commonly used. Borax can be added directly to the pool water in small increments, followed by thorough mixing and retesting of pH levels.
While these natural methods can help adjust swimming pool pH levels without the use of traditional chemicals, they may not always be as precise or efficient as chemical treatments. It's essential to monitor pH levels regularly and be prepared to supplement natural methods with appropriate chemical adjustments when necessary to ensure proper water balance and sanitation. Consulting with a pool professional can also provide guidance on the most effective and suitable methods for maintaining optimal pool pH levels.
