However, the overall best is a powered rod. Both types can handle the high mineral content, though powered rods usually provide better protection against corrosion, limescale buildup, and smell.<\/strong> <\/p><\/div>\n\n\n<h2 class=\"wp-block-heading\">Hard Water Is Very Corrosive<\/h2>\n\n\n\n<p>Hard water gains its name from the type of minerals it contains. Hard water, in comparison to soft water, has a higher pH level and contains a higher concentration of minerals, primarily calcium and magnesium, though others may be present.<\/p>\n\n\n\n<p>In other words, the fewer minerals are in the water, the softer it is.<\/p>\n\n\n\n<p>Even though hard water has a lower corrosion rate than soft water, it doesn&rsquo;t mean that it doesn&rsquo;t cause corrosion at all. It just does so in a different way.<\/p>\n\n\n\n<p>The minerals can also build up on various surfaces over time. This increases the tendency of the tank to corrode since <strong>mineral buildup on the inside of water tanks can wear away at the top layer of the steel, making it much more prone to rust.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hard Water Causes Limescale<\/h2>\n\n\n\n<p>Limescale, as mentioned, is a buildup of minerals, primarily calcium carbonate. Once the water evaporates, it leaves behind the minerals it contains, allowing them to build up over time and form a hard, thick layer of deposit.&nbsp;&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><noscript><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup.jpg\" alt=\"hard water causes limescale buildup\" class=\"wp-image-14883\" width=\"738\" height=\"538\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-735x536.jpg 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-335x244.jpg 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-347x253.jpg 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-520x379.jpg 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-640x467.jpg 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-960x700.jpg 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup.jpg.webp\" alt=\"hard water causes limescale buildup\" class=\"wp-image-14883 lazyload\" width=\"738\" height=\"538\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-735x536.jpg.webp 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-335x244.jpg.webp 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-347x253.jpg.webp 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-520x379.jpg.webp 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-640x467.jpg.webp 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup-960x700.jpg.webp 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/04\/hard-water-causes-limescale-buildup.jpg\" id=\"mv-trellis-img-2\" data-trellis-processed=\"1\"><\/figure><\/div>\n\n\n<p><strong>Since hard water contains higher concentrations of minerals, the harder the water, the faster it creates limescale buildup.<\/strong><\/p>\n\n\n\n<p>Limescale is not harmful to our health, but as it develops, it can become a problem. This is especially true for appliances like water heaters.<\/p>\n\n\n\n<p>Over time, <strong>limescale buildup will surround a water heater&rsquo;s heating element. This forces it to warm through the limescale in order to heat the water, making it work harder and less efficiently to do its job<\/strong>. This can reduce the heater&rsquo;s lifespan by several years.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">There Are Several Types of Anode Rods<\/h2>\n\n\n\n<p>There are two primary categories of anode rods.

It keeps corrosion at bay by using electrical pulses to prevent corrosion and limescale buildup inside the tank.<\/p>\n\n\n\n<p>Sacrificial anode rods, on the other hand, are thus named because they draw corrosive elements towards themselves.
