Dissolved metals interfere with biguanide sanitizer and clarifier, quietly consuming them and shortening how long a residual holds. On a program where the sanitizer is the single most expensive recurring product, metals in the water are costing you money every week whether or not you ever see a stain.\u003c\/p\u003e\n\u003cp\u003eThere's one requirement that's easy to miss and expensive to skip:\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eStain Control must be used when starting a white plaster pool on SoftSwim B — whether metals are present or not.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThat's not a recommendation scaled to your water test.

BioGuard states it plainly, and the reason is that fresh white plaster is both the surface most likely to show staining and the one where a stain is hardest to remove. A start-up without Stain Control on a new plaster finish is the sort of shortcut that shows up as permanent discoloration on a brand-new surface, discovered weeks later when the only remaining options are a full stain protocol or an acid wash. Get the water tested by a dealer before start-up, add the Stain Control regardless of the result, and the finish stays clean.\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":67305590358265,"sku":"lge1791365064105","price":18.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5484\/2105\/files\/bioguard-softswim-stain-control-stain-preventer_1.jpg?v=1791365070","url":"https:\/\/buyzenvilo.com\/products\/bioguard-softswim-stain-control-stain-preventer","provider":"Buyzenvilo","version":"1.0","type":"link"}
