By keeping hardness in the recommended range (commonly about 200–400 ppm, minimum around 150 ppm), it supports long‑term protection of plaster, vinyl, and equipment while improving overall water balance.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eKey features \u0026amp; benefits\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDurable calcium protection helps stop water from leaching calcium out of plaster, grout, concrete, and some vinyl-backed surfaces, reducing pitting and structural wear.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOptimized water balance works alongside pH, alkalinity, and sanitizer to keep water chemistry stable and easier to manage.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEquipment longevity by reducing corrosive conditions that can attack heaters, ladders, handrails, and metal fittings when hardness is too low.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLarge 15 lb size is ideal for full openings, large pools, or step‑up corrections when hardness is significantly below target.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse \u0026amp; basic dosing approach\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWhen to use: At opening, after significant water replacement or heavy rain dilution, or whenever testing shows hardness below the recommended minimum.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTypical target range: Many pool pros recommend keeping calcium hardness between about 200–400 ppm, with a minimum around 150 ppm to avoid corrosive water.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eGeneral dosing concept:\u003c\/li\u003e\n\u003cli\u003eTest calcium hardness first with a reliable kit.\u003c\/li\u003e\n\u003cli\u003eCalculate how many ppm you need to raise based on pool volume.\u003c\/li\u003e\n\u003cli\u003eBroadcast measured product around the pool with the pump running, allow to circulate fully, then retest before adding more to avoid overshooting and potential scale.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLifeLine Calcium Hardness Increaser 15 lb fits neatly into a professional balancing program, giving you a simple way to protect your pool surfaces and hardware while supporting clear, comfortable water.\u003cbr\u003e\u003c\/p\u003e","brand":"ROBELLE INDUSTRIES","offers":[{"title":"Default Title","offer_id":45623494574380,"sku":"2815BGT","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/8594\/0780\/products\/15.jpg?v=1688913011","url":"https:\/\/www.budgetpools.com\/products\/calcium-hardness-increaser-15lb","provider":"Budget Pools","version":"1.0","type":"link"}
