It is ideal for freshwater and marine hobbyists who want clearer water, lower organic loading and a reusable chemical filter media with long service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat It Does\u003c\/strong\u003e\u003cbr\u003ePurigen targets nitrogen-based organic waste in the water column, helping reduce the source of harmful compounds rather than only dealing with them after they appear. It also improves water clarity and has minimal effect on trace elements, making it a popular choice for display tanks where clean, polished water matters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-capacity organic removal resin\u003c\/li\u003e\n\u003cli\u003eHelps control ammonia, nitrite and nitrate by removing waste before breakdown\u003c\/li\u003e\n\u003cli\u003ePolishes aquarium water for exceptional clarity\u003c\/li\u003e\n\u003cli\u003eMacro-porous structure with very large usable surface area\u003c\/li\u003e\n\u003cli\u003eColour changes as it becomes exhausted, making replacement timing easy\u003c\/li\u003e\n\u003cli\u003eRegenerable for repeated use\u003c\/li\u003e\n\u003cli\u003eSuitable for both marine and freshwater aquariums\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Aquarists Choose It\u003c\/strong\u003e\u003cbr\u003eUnlike standard ion-exchange media, Purigen is designed specifically to attract organic waste. Its spherical, macroreticular bead structure includes microscopic pores that increase working surface area well beyond that of ordinary smooth resin beads. This gives it strong performance in tanks with fish, corals or plants that continuously produce organic waste.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Use\u003c\/strong\u003e\u003cbr\u003eRinse before use and place the media in a fine mesh filter bag. Use in your filter where water can flow through it effectively. Exhaustion is shown by a clear colour shift from pale blonde to dark brown or black.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDosing and Capacity\u003c\/strong\u003e\u003cbr\u003eEach 1 litre treats up to 4,000 litres of aquarium water for up to six months, depending on bioload and water conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRegeneration\u003c\/strong\u003e\u003cbr\u003eSoak exhausted Purigen in a 1:1 bleach:water solution for 24 hours in a non-metallic container, in a well-ventilated area and away from children. Use regular 8.25% hypochlorite household bleach only; it must be unscented, contain no dyes and must not be splash-less bleach. Rinse well, then soak for 8 hours in a solution containing 4 tablespoons of Prime or an equivalent dechlorinator per cup of water. Rinse well again. For freshwater use, soak for 4 hours in a solution containing 2 tablespoons of buffer per cup of water, such as Discus Buffer or Neutral Regulator. Do not reuse if any bleach or chlorine smell remains.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Notes\u003c\/strong\u003e\u003cbr\u003eSome slime coat products may permanently foul the resin and make regeneration difficult. If unsure after regeneration, soak the beads in a small quantity of water and test for residual chlorine before placing them back into the aquarium.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003cbr\u003eSeachem Purigen filter media.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use Seachem Purigen in freshwater and marine aquariums?\u003c\/strong\u003e\u003cbr\u003eYes. Purigen is designed for both freshwater and marine use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know when Purigen is exhausted?\u003c\/strong\u003e\u003cbr\u003eThe beads gradually darken from a pale blonde colour to dark brown or nearly black. That pronounced discolouration indicates it is time to regenerate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much water does Seachem Purigen treat?\u003c\/strong\u003e\u003cbr\u003eEach 1 litre treats up to 4,000 litres of water for up to six months, although actual lifespan depends on stocking levels and how much organic waste your tank produces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan Purigen help with ammonia, nitrite and nitrate?\u003c\/strong\u003e\u003cbr\u003eYes. It helps control these by removing nitrogenous organic waste before that waste decomposes and releases ammonia, which can then lead to nitrite and nitrate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat bleach should I use to regenerate Purigen?\u003c\/strong\u003e\u003cbr\u003eUse regular 8.25% hypochlorite household bleach only. It must be non-scented, contain no dyes and must not be a splash-less bleach.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs Seachem Purigen reusable?\u003c\/strong\u003e\u003cbr\u003eYes. Once exhausted, it can be regenerated using the bleach-and-water method, followed by dechlorinator treatment and, for freshwater use, a buffer soak before reuse.\u003c\/p\u003e","brand":"AD","offers":[{"title":"100ml Bagged","offer_id":39279163080758,"sku":"000116016506","price":342.0,"currency_code":"ZAR","in_stock":true},{"title":"250ml","offer_id":39279163113526,"sku":"000116016605","price":569.0,"currency_code":"ZAR","in_stock":true},{"title":"1L","offer_id":49206941712692,"sku":"000116016704","price":2080.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0151\/9016\/3510\/files\/SeachemPurigen100mlBagged.png?v=1785590857","url":"https:\/\/jungleaquatics.com\/products\/seachem-purigen","provider":"Jungle Aquatics Pet Store","version":"1.0","type":"link"}
