Running it until it's actually spent — rather than on a calendar guess — is the only way to guarantee 0 TDS water for coral-safe top-off, and the built-in color change is what tells you when that point has arrived.\u003c\/p\u003e\u003cp\u003eIncludes: 7.5 lbs of loose-fill virgin DI resin (media only, no cartridge or housing included).\u003c\/p\u003e\u003cp\u003eCompatible with: IceCap 4-stage RO\/DI systems (IC-RI75, IC-RI100, IC-RI150, IC-RI200) and most other DI reactors\/cartridges sized for standard mixed-bed resin.\u003c\/p\u003e","brand":"IceCap","offers":[{"title":"Default Title","offer_id":45979590688812,"sku":"IC-RI-DIRES75","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4382\/5196\/files\/icecap_deionization_resin_ba65f28c-36d9-41e9-8659-321884a4e972.jpg?v=1787011399","url":"https:\/\/www.marineconceptsupply.com\/products\/7-5lbs-icecap-deionization-resin-6-fill-ic-ri-dires75","provider":"Marine Concept Supply","version":"1.0","type":"link"}
