It is a water balancing chemical, not a sanitizer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it fixes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTotal alkalinity is the buffer that keeps pH from wandering. When alkalinity falls, pH swings on every rainstorm, every chemical addition and every busy weekend, and chasing it with acid or soda ash becomes a losing game. Bringing alkalinity back into range steadies the whole picture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTarget ranges\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eProteam lists total alkalinity of 125 to 150 ppm for vinyl and fiberglass pools. Their guidance for plaster and similar surfaces is stated as calcium hardness of 100 to 150 ppm, so read the container instructions alongside your own test results before dosing a plaster pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it protects equipment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater held in balance is far less likely to turn corrosive or to start dropping scale. Both extremes cost money, one by eating at surfaces, fittings and heater internals, the other by coating them. Keeping alkalinity in range is the cheapest part of avoiding either.\u003c\/p\u003e","brand":"Proteam","offers":[{"title":"Default Title","offer_id":48628810907860,"sku":"PTM-50-7225","price":74.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5aab84fc-0db7-4c6a-8a1f-ebc244c6a9e1.jpg?v=1788752213","url":"https:\/\/www.activepoolsupply.com\/products\/alkalinity-up-25lbs","provider":"Active Pool Supply","version":"1.0","type":"link"}
