But did you know there are different types of chlorine measurements? Understanding the difference between <strong>total chlorine<\/strong> and <strong>combined chlorine<\/strong> can help you prevent cloudy water, eliminate unpleasant odors, and keep your pool safe for swimming.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>L&amp;J Pools<\/strong>, we recommend using <strong>ProTeam Pool Chemicals<\/strong> as part of a complete water care program to help homeowners maintain balanced, crystal-clear water all season long.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Free Chlorine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Free chlorine is the chlorine in your pool that is actively sanitizing the water. It destroys bacteria, algae, viruses, and other contaminants before they become a problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For most residential pools, free chlorine should be maintained between <strong>1\u20133 ppm<\/strong>, depending on your cyanuric acid (stabilizer) level and how heavily the pool is being used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without enough free chlorine, your pool can quickly become cloudy or develop algae.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Total Chlorine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Total chlorine<\/strong> is the total amount of chlorine present in your pool water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It consists of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\"><strong>Free Chlorine (FC)<\/strong> \u2013 the chlorine actively sanitizing the water.<\/li>\n\n\n\n<li class=\"\"><strong>Combined Chlorine (CC)<\/strong> \u2013 chlorine that has already reacted with contaminants.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The formula is simple:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Total Chlorine = Free Chlorine + Combined Chlorine<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Free Chlorine: 2.5 ppm<\/li>\n\n\n\n<li class=\"\">Combined Chlorine: 0.5 ppm<\/li>\n\n\n\n<li class=\"\">Total Chlorine: 3.0 ppm<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A total chlorine reading alone doesn&#8217;t tell the whole story. The key is understanding how much of that chlorine is still working for you.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Combined Chlorine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Combined chlorine, often called <strong>chloramines<\/strong>, forms when free chlorine reacts with contaminants introduced by swimmers and the environment, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Sweat<\/li>\n\n\n\n<li class=\"\">Sunscreen<\/li>\n\n\n\n<li class=\"\">Body oils<\/li>\n\n\n\n<li class=\"\">Urine<\/li>\n\n\n\n<li class=\"\">Leaves<\/li>\n\n\n\n<li class=\"\">Dirt and pollen<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Once chlorine combines with these contaminants, it becomes much less effective at sanitizing your pool.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Combined Chlorine a Problem?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">High combined chlorine levels can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Strong chlorine odor<\/li>\n\n\n\n<li class=\"\">Burning eyes<\/li>\n\n\n\n<li class=\"\">Skin irritation<\/li>\n\n\n\n<li class=\"\">Cloudy water<\/li>\n\n\n\n<li class=\"\">Reduced sanitizer effectiveness<\/li>\n\n\n\n<li class=\"\">Increased risk of algae growth<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many people believe that a pool smelling strongly of chlorine has too much chlorine. In reality, that odor is usually caused by <strong>high combined chlorine<\/strong>, not excessive free chlorine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A properly balanced pool should have very little chlorine smell.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Should Combined Chlorine Be?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ideally, combined chlorine should measure:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>0.0 ppm<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anything below <strong>0.2 ppm<\/strong> is generally acceptable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If combined chlorine reaches <strong>0.5 ppm or higher<\/strong>, it&#8217;s time to oxidize the contaminants by shocking the pool.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Remove Combined Chlorine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The best way to eliminate combined chlorine is through <strong>breakpoint chlorination<\/strong>, commonly known as shocking the pool.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L&amp;J Pools recommends using quality sanitizers and oxidizers along with <strong>ProTeam Pool Chemicals<\/strong> to keep your water balanced before problems develop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Maintaining proper water balance allows chlorine to work more efficiently, meaning you use less sanitizer over time while enjoying cleaner, clearer water.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How ProTeam Pool Chemicals Help<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Keeping chlorine effective isn&#8217;t just about adding more chlorine\u2014it&#8217;s about maintaining balanced water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why L&amp;J Pools proudly recommends <strong>ProTeam Pool Chemicals<\/strong>, a trusted name in professional water care.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some of our favorite ProTeam products include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">ProTeam Supreme Plus<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Supreme Plus helps improve overall water quality by conditioning the water and making it easier to maintain proper chemical balance.
