Swimming pools should maintain a <strong>pH level between 7.4 and 7.6<\/strong> to keep swimmers comfortable while still effectively sanitizing. Anything below 7.2 is considered too low and should be adjusted.&nbsp;<\/p>\n\n\n\n<p>Acidic pool water can sting eyes and skin, corrode equipment, damage your pool\u2019s plaster or grout, and cause the pool to use chlorine too rapidly. It can occur as a result of heavy rainfall, debris in the pool, or even products like sunscreen from swimmers\u2019 bodies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"1-four-methods-for-raising-the-ph-in-a-pool\">Four Methods for Raising the pH in a Pool<\/h2>\n\n\n\n<p>Here are four proven methods to increase your pool&#8217;s pH level.

While shock treatments do raise pH levels, you can&#8217;t control how much. Shock also changes other chemical levels at the same time, making it harder to balance your pool water properly.\u00a0<br\/><\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1747464380541\"><strong class=\"schema-faq-question\">Does rain raise the pH in pools?<\/strong> <p class=\"schema-faq-answer\">No, rain typically <em>lowers<\/em> pH in pools. Rainwater is naturally acidic (around 5.6 pH) due to dissolved carbon dioxide, which forms carbonic acid. After heavy rainfall, it&#8217;s important to test your pool&#8217;s pH and adjust as necessary, as it will likely be lower than before.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1747464394474\"><strong class=\"schema-faq-question\">How can I raise pH in a pool without raising alkalinity?<\/strong> <p class=\"schema-faq-answer\">Borax and aeration are the best methods to raise pH with minimal impact on alkaline levels:<br\/><br\/><strong>\u2022<\/strong> <strong>Borax: <\/strong>Adds hydroxide ions to the water, raising pH with little effect on alkalinity.<br\/><strong><strong>\u2022<\/strong><\/strong> <strong>Aeration:<\/strong> Carbon dioxide is released when you circulate the water, naturally raising pH without affecting the alkalinity.<\/p> <\/div> <\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"7-expert-pool-ph-management\">Expert Pool pH Management<\/h2>\n\n\n\n<p>Now that you have all the knowledge needed to maintain your pool&#8217;s perfect pH balance, you&#8217;re ready to take action.
