{"product_id":"boyd-chemi-pure-the-original-carbon-resin-blend","title":"Boyd Chemi-Pure — The Original Carbon \u0026 Resin Blend","description":"\u003cp\u003e\u003cstrong\u003eThis is the media that has been in continuous production since 1961, and it is still in my sumps.\u003c\/strong\u003e Chemi-Pure predates most of what gets sold as \"advanced filtration\" today, and it has outlasted almost all of it for a simple reason: it is not one thing. It is a blended media that handles organics, metals, and pH drift in a single bag, which means one pouch does the work three separate reactors are usually sold to do.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is actually in the bag\u003c\/h3\u003e\n\u003cp\u003ePremium activated carbon does the bulk of the work — it pulls dissolved organic compounds, phenols, and the yellowing tannins that make water look tired before you consciously notice it. Alongside the carbon sit ion-exchange resins, and those are the part people overlook. Resins grab what carbon cannot: dissolved heavy metals, copper, and ammonia that slips through as a system swings. The blend also buffers, holding pH steadier than carbon alone would.\u003c\/p\u003e\n\u003cp\u003eThe practical result is water that stays optically clear and chemically boring. Boring is the goal. A tank that never spikes and never yellows is a tank whose inhabitants are spending their energy on growth and color instead of on coping.\u003c\/p\u003e\n\n\u003ch3\u003eHow I actually use it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRinse first.\u003c\/strong\u003e Run tap or tank water through the bag until it runs clear. Carbon dust is harmless but it will cloud a display for a day and irritate gills on the way through.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlace it in flow.\u003c\/strong\u003e A canister basket, a media chamber, or laid in the sump where water is actually moving through it, not past it. Media sitting in dead water is decoration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e the 5 oz treats roughly 35 gallons, the 10 oz roughly 75 gallons, and the Grande 40 oz is for the systems where you would otherwise be stacking four bags.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplace every 4 months.\u003c\/strong\u003e Carbon exhausts quietly — it does not announce itself, it just stops working while continuing to look exactly the same.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe honest caveat\u003c\/h3\u003e\n\u003cp\u003eChemi-Pure Original is a general-purpose blend, and general-purpose means it does not specialize. If your problem is specifically phosphate, you want \u003ca href=\"\/products\/boyd-chemi-pure-elite-carbon-resin-gfo-in-one-bag\"\u003eChemi-Pure Elite\u003c\/a\u003e, which adds ferric oxide hydroxide to bind it. If you are running a planted freshwater tank and dosing ferts, the Original will strip some of what you just paid for — \u003ca href=\"\/products\/boyd-chemi-pure-green-filter-media\"\u003eChemi-Pure Green\u003c\/a\u003e exists for exactly that reason. On a reef, \u003ca href=\"\/products\/boyd-chemi-pure-blue-reef-marine-media\"\u003eChemi-Pure Blue\u003c\/a\u003e is the gentler choice.\u003c\/p\u003e\n\u003cp\u003eAlso worth saying plainly: pull it before you medicate. Carbon does not care that the compound in the water is one you added on purpose. It will strip a treatment out of the water column just as efficiently as it strips waste, and you will spend the money without getting the dose.\u003c\/p\u003e","brand":"Boyd Enterprises","offers":[{"title":"5 oz (treats ~35 gal)","offer_id":50593318502637,"sku":"BOYD-CP-5OZ","price":7.99,"currency_code":"USD","in_stock":false},{"title":"10 oz (treats ~75 gal)","offer_id":50593318535405,"sku":"BOYD-CP-10OZ","price":11.99,"currency_code":"USD","in_stock":false},{"title":"Grande 40 oz","offer_id":50593318568173,"sku":"BOYD-CP-GRANDE40","price":43.99,"currency_code":"USD","in_stock":false},{"title":"10 oz — Bulk 6 Pack","offer_id":50593318600941,"sku":"BOYD-CP-10OZ-6PK","price":53.99,"currency_code":"USD","in_stock":false}],"url":"https:\/\/www.yocamronsaquatics.com\/products\/boyd-chemi-pure-the-original-carbon-resin-blend","provider":"YoCamron's Aquatics","version":"1.0","type":"link"}
