It's an easy fix for one of the most overlooked balance problems in spa care: water that's too soft. When calcium runs low, the water turns aggressive and starts looking for minerals to dissolve — pulling them out of your equipment and surfaces instead.\u003c\/p\u003e\n\u003cp\u003eLow-calcium water causes three real problems. It corrodes metal components like the heater and fittings, it can etch and damage spa surfaces, and it tends to foam. Maintaining a proper calcium hardness level protects your spa from all three. Calcium is one of the three core balance numbers — alongside pH and total alkalinity — and keeping it in range is part of water that's gentle on both your spa and the people in it.\u003c\/p\u003e\n\u003cp\u003eThis granular formula dissolves into the water to bring soft water back up to a protective level, and it works with every common sanitizing system.\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIf you've refilled with soft or filtered water and you're battling stubborn foam that defoamer only fixes temporarily, check your calcium hardness before reaching for more chemicals. Low calcium is a frequent hidden cause of foaming — and raising hardness solves it at the source.\u003cmeta charset=\"utf-8\"\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cp\u003e\u003cspan aria-label=\"®\" role=\"img\"\u003eSpaGuard®\u003c\/span\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SpaGuard","offers":[{"title":"Default Title","offer_id":31289911967799,"sku":"42636BIO","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2507\/5288\/products\/SpaGuard_Calcium-Increaser-12-oz_White.png?v=1675292825","url":"https:\/\/leisuretimeinc.com\/products\/spaguard-calcium-hardness-increaser","provider":"Leisure Time Inc.","version":"1.0","type":"link"}
