{"product_id":"seachem-purigen-organic-filtration-resin-fresh-and-saltwater-100-ml","title":"Regenerable Aquarium Filtration Resin for Freshwater and Saltwater Tanks, 100 or 500 ml – Seachem Purigen","description":"\u003cp\u003eRegenerable aquarium filtration resin removes nitrogenous organic waste before it breaks down into ammonia, nitrite, and nitrate. Seachem Purigen uses a premium synthetic polymer adsorbent for freshwater or saltwater systems, helping polish water clarity while having minimal stated impact on trace elements. The pale resin progressively darkens toward brown or nearly black as it becomes exhausted, giving aquarists a visible cue to service the media.\u003c\/p\u003e\u003cp\u003eChoose 100 or 500 milliliters according to the aquarium volume and filter configuration, then place and use the granules only as directed on the product label. Purigen can be regenerated after exhaustion, but the process involves bleach and requires exact chemical handling, rinsing, dechlorination, and safety steps. Never improvise a ratio, mix bleach with other cleaners, or return incompletely regenerated media to livestock. Replace the resin when regeneration is unsuitable or the material no longer performs as expected.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Seachem\u003c\/li\u003e\n\u003cli\u003eProduct: Regenerable aquarium filtration resin\u003c\/li\u003e\n\u003cli\u003eMaterial: Synthetic polymer adsorbent\u003c\/li\u003e\n\u003cli\u003eForm: Granules\u003c\/li\u003e\n\u003cli\u003eSizes: 100 or 500 milliliters\u003c\/li\u003e\n\u003cli\u003eWater types: Freshwater and saltwater\u003c\/li\u003e\n\u003cli\u003ePrimary action: Adsorbs nitrogenous organic waste\u003c\/li\u003e\n\u003cli\u003eRelated water parameters: Helps prevent waste from releasing ammonia, nitrite, and nitrate\u003c\/li\u003e\n\u003cli\u003eAppearance when fresh: Pale blonde\u003c\/li\u003e\n\u003cli\u003eAppearance when exhausted: Dark brown to nearly black\u003c\/li\u003e\n\u003cli\u003eRegeneration: Supported according to exact label directions\u003c\/li\u003e\n\u003cli\u003eDetailed 100 ml weight: 2.24 ounces\u003c\/li\u003e\n\u003cli\u003eDetailed model: 165\u003c\/li\u003e\n\u003cli\u003eUse: Aquarium filter media\u003c\/li\u003e\n\u003c\/ul\u003e\u003csection class=\"product-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhat does Seachem Purigen remove?\u003c\/h3\u003e\n\u003cp\u003ePurigen adsorbs nitrogenous organic waste before that waste can release ammonia, nitrite, and nitrate into aquarium water.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eCan I use it in both freshwater and saltwater tanks?\u003c\/h3\u003e\n\u003cp\u003eYes.
