While those are essential, <strong>total hardness<\/strong> is another important water balance factor that shouldn&#8217;t be overlooked. Keeping your pool&#8217;s hardness level within the proper range helps protect your equipment, your pool surface, and even your swimmers&#8217; comfort.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Total Hardness?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Total hardness<\/strong> measures the amount of dissolved minerals in your pool water, primarily <strong>calcium and magnesium<\/strong>. In the pool industry, you&#8217;ll often hear people refer to <strong>calcium hardness<\/strong>, since calcium is the most significant mineral affecting pool water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These minerals naturally enter your pool through:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Fill water<\/li>\n\n\n\n<li class=\"\">Rainwater<\/li>\n\n\n\n<li class=\"\">Certain pool chemicals<\/li>\n\n\n\n<li class=\"\">Groundwater intrusion<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">While some hardness is necessary, both low and high levels can create expensive problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Total Hardness Important?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Balanced hardness helps protect your entire pool system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If Total Hardness Is Too Low<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Water with low hardness becomes &#8220;hungry&#8221; for minerals. It will try to pull calcium from wherever it can, including your pool&#8217;s plaster, grout, stone, and concrete surfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Low hardness can cause:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Surface etching<\/li>\n\n\n\n<li class=\"\">Rough plaster<\/li>\n\n\n\n<li class=\"\">Damaged tile grout<\/li>\n\n\n\n<li class=\"\">Corrosion of metal components<\/li>\n\n\n\n<li class=\"\">Shortened equipment life<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The result is costly repairs that could have been prevented with proper water balance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If Total Hardness Is Too High<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive hardness causes calcium to come out of solution and form deposits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">High hardness can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">White scale buildup on pool walls<\/li>\n\n\n\n<li class=\"\">Calcium deposits on tile<\/li>\n\n\n\n<li class=\"\">Cloudy water<\/li>\n\n\n\n<li class=\"\">Clogged filters<\/li>\n\n\n\n<li class=\"\">Reduced heater efficiency<\/li>\n\n\n\n<li class=\"\">Damage to pumps and other equipment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Scale buildup not only looks unattractive but can also reduce the lifespan of expensive pool equipment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the Ideal Total Hardness Level?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For most residential pools, the recommended calcium hardness range is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\"><strong>Concrete &amp; Plaster Pools:<\/strong> <strong>200\u2013400 ppm<\/strong><\/li>\n\n\n\n<li class=\"\"><strong>Vinyl Liner Pools:<\/strong> <strong>150\u2013250 ppm<\/strong><\/li>\n\n\n\n<li class=\"\"><strong>Fiberglass Pools:<\/strong> <strong>175\u2013300 ppm<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The ideal level can vary slightly depending on your pool type, local water source, and other water chemistry factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Test Total Hardness?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most accurate way is with a professional liquid test kit or by having your water tested by a pool professional.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>L&amp;J Pools<\/strong>, we recommend testing your water regularly\u2014especially:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">At pool opening<\/li>\n\n\n\n<li class=\"\">During mid-season<\/li>\n\n\n\n<li class=\"\">After large water additions<\/li>\n\n\n\n<li class=\"\">Before closing your pool<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Regular testing helps catch problems before they become expensive repairs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Raise Total Hardness?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If your hardness is low, the solution is usually adding a <strong>calcium hardness increaser<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We recommend using <strong>ProTeam Calcium Up<\/strong>, a high-quality calcium chloride product designed to safely increase calcium hardness while helping maintain balanced water chemistry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always add the product according to the manufacturer&#8217;s directions and retest the water after treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Lower Total Hardness?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike raising hardness, lowering it isn&#8217;t as simple as adding a chemical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common solutions include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Partially draining and refilling the pool with lower-hardness water<\/li>\n\n\n\n<li class=\"\">Using specialized water treatment methods<\/li>\n\n\n\n<li class=\"\">Preventing additional calcium buildup through proper water balance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Maintaining proper pH, total alkalinity, and overall water balance can also help minimize scaling even if hardness is on the higher end.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Total Hardness Works With the Rest of Your Water Chemistry<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Total hardness doesn&#8217;t work alone. It should always be balanced alongside:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">pH<\/li>\n\n\n\n<li class=\"\">Total Alkalinity<\/li>\n\n\n\n<li class=\"\">Free Chlorine<\/li>\n\n\n\n<li class=\"\">Combined Chlorine<\/li>\n\n\n\n<li class=\"\">Cyanuric Acid (Stabilizer)<\/li>\n\n\n\n<li class=\"\">Salt (for saltwater pools)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When all of these levels work together, your pool water stays clear, comfortable, and easier to maintain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Let L&amp;J Pools Help Keep Your Water Balanced<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Testing and balancing pool chemistry can feel overwhelming, but it doesn&#8217;t have to be.
