CerMedia states a single POD carries the equivalent surface area of over 5,000 plastic bio-balls, and sells them in a 3-pack sized for a canister filter or small sump, or a 24-pack sized for a full sump or large canister setup.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquivalent to 5,000+ bio-balls per POD\u003c\/strong\u003e — CerMedia's own comparison figure for the surface area a single POD carries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublished bioload ratings\u003c\/strong\u003e — CerMedia rates the 3-pack to 100 US gallons and the 24-pack to 750 US gallons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResists clogging\u003c\/strong\u003e — the rigid ceramic structure holds its shape, so flow through the media stays consistent between cleans.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusable\u003c\/strong\u003e — rinse in tank water at a water change rather than replacing on a schedule.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSits loose or bagged\u003c\/strong\u003e — large enough to sit directly in a sump compartment, or contained in a MarinePure Mesh Bag for easy handling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMarinePure (CerMedia, USA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePod diameter\u003c\/th\u003e\n\u003ctd\u003eApprox. 8 cm (3.1\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eInert aluminosilicate ceramic, fired above 1,000°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOpen porosity\u003c\/th\u003e\n\u003ctd\u003e80–90%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSurface area\u003c\/th\u003e\n\u003ctd\u003eEquivalent to over 5,000 plastic bio-balls, per POD (CerMedia comparison figure)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater type\u003c\/th\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eWhich pack size do I need?\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePack\u003c\/th\u003e\n\u003cth\u003eCerMedia bioload rating\u003c\/th\u003e\n\u003cth\u003eBest suited to\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3-pack\u003c\/td\u003e\n\u003ctd\u003eUp to 100 US gallons (380 L)\u003c\/td\u003e\n\u003ctd\u003eA canister filter or small sump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24-pack\u003c\/td\u003e\n\u003ctd\u003eUp to 750 US gallons (2,839 L)\u003c\/td\u003e\n\u003ctd\u003eA full sump or large display system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eBoth packs use the same POD, so there's no difference in performance per piece — only in how much total surface area you're buying.

Standard parcel freight applies; the 24-pack is heavier and may attract a higher freight quote at checkout, though it ships as standard parcel post.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003ch4\u003eDo I need a mesh bag for PODs?\u003c\/h4\u003e\u003cp\u003eNot necessarily — PODs are large enough to sit loose in a sump compartment or media rack. A Mesh Bag makes them easier to lift out for a rinse, but isn't required for them to work.\u003c\/p\u003e\u003ch4\u003eCan I mix POD pack sizes to reach a specific bioload target?\u003c\/h4\u003e\u003cp\u003eYes — CerMedia's bioload ratings scale with the number of PODs, so combining a 3-pack and a 24-pack, or buying multiple 3-packs, is a valid way to size up gradually.\u003c\/p\u003e\u003ch4\u003eAre PODs reef safe?\u003c\/h4\u003e\u003cp\u003eYes, the ceramic is inert and safe for reef and marine systems as well as freshwater.\u003c\/p\u003e\u003ch4\u003eDo I need to cycle a filter before adding livestock?\u003c\/h4\u003e\u003cp\u003eYes. Any new biomedia needs time for bacteria to colonise the ceramic before it's doing useful biological work. Run it on established tank water, or fishless-cycle with an ammonia source, before stocking up.\u003c\/p\u003e","brand":"MarinePure","offers":[{"title":"3pk","offer_id":54773874393379,"sku":"124739","price":48.95,"currency_code":"AUD","in_stock":false},{"title":"24pk","offer_id":55335328088355,"sku":"124740","price":238.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/marinepure-pods-43160125931811.webp?v=1790237816","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/marinepure-pods","provider":"Nicks AOT","version":"1.0","type":"link"}
