Minerals dissolved in water are invisible and harmless. The trouble begins when conditions shift — a rise in pH, a temperature increase, a chlorine addition — and those minerals come out of solution and deposit onto whatever surface they land on. Calcium becomes the white, crusty scale that builds on tile and roughens plaster. Iron and copper become brown, green, or black staining that brushing won't touch.\u003c\/p\u003e\n\u003cp\u003eThe most expensive place either one shows up is the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eheater\u003c\/strong\u003e. Scale on a heat exchanger insulates it, forcing longer run times, driving up gas or electric costs, and eventually causing failure. A sequestrant is dramatically cheaper than a heat exchanger.\u003c\/p\u003e\n\u003cp\u003eThis formulation has been\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ereformulated and is four times more effective\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethan the previous version, and it keeps working\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ethree to four weeks after application\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— so a monthly maintenance dose actually covers the month.

Chlorine is a powerful oxidizer, and raising the chlorine level is exactly what knocks dissolved iron and copper out of solution and onto your pool surface. That's why stains so often appear right after opening or right after a shock treatment — the metal was there the whole time, waiting for something to precipitate it. If you're filling from a well, or topping off substantially, dose the sequestrant first and let it circulate before adding sanitizer. Five minutes of sequence discipline prevents a stain that costs a full treatment protocol to remove.\u003c\/p\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 role=\"img\"\u003eBioGuard®\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BioGuard","offers":[{"title":"Default Title","offer_id":67305577939193,"sku":"pvd1791364963061","price":18.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5484\/2105\/files\/bioguard-scale-inhibitor-scale-stain-preventer_1.jpg?v=1791364968","url":"https:\/\/buyzenvilo.com\/products\/bioguard-scale-inhibitor-scale-stain-preventer","provider":"Buyzenvilo","version":"1.0","type":"link"}
