The open, interconnected pore structure gives bacteria a huge surface to colonise, so a modest volume of spheres does the biological filtration work of a much larger volume of plastic media — and the deep pores support the low-oxygen zones that also help bring nitrate down.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-porous ceramic\u003c\/strong\u003e — fired above 1,000°C, inert, and never leaches into the water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandles ammonia and nitrite\u003c\/strong\u003e — the primary biological filtration job, at high flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelps reduce nitrate\u003c\/strong\u003e — deep pores create low-oxygen zones plastic bio-balls can't replicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree-pours into any filter\u003c\/strong\u003e — canister filters, sumps, wet\/dry towers and trickle filters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreshwater and marine\u003c\/strong\u003e — the same media works in either\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNever needs replacing\u003c\/strong\u003e — inert ceramic doesn't wear out or break down biologically\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003cth\u003eApprox. media volume\u003c\/th\u003e\n\u003cth\u003eSuitability\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1.9 L Box\u003c\/td\u003e\n\u003ctd\u003e100892\u003c\/td\u003e\n\u003ctd\u003e2 US quarts\u003c\/td\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3.8 L Box\u003c\/td\u003e\n\u003ctd\u003e100893\u003c\/td\u003e\n\u003ctd\u003e1 US gallon\u003c\/td\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e18.9 L Bucket\u003c\/td\u003e\n\u003ctd\u003e102688\u003c\/td\u003e\n\u003ctd\u003e5 US gallons\u003c\/td\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e56 L Half-Drum\u003c\/td\u003e\n\u003ctd\u003e102666\u003c\/td\u003e\n\u003ctd\u003e~15 US gallons\u003c\/td\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 L Drum\u003c\/td\u003e\n\u003ctd\u003e100896\u003c\/td\u003e\n\u003ctd\u003e~26 US gallons\u003c\/td\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eHow much filtration does it provide?\u003c\/h3\u003e\u003cp\u003eCerMedia rates MarinePure media at roughly 1 part media to 500 parts tank water for ongoing ammonia and nitrite control, so the tank volume a pack supports scales directly with the pack size:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePack\u003c\/th\u003e\n\u003cth\u003eMedia volume\u003c\/th\u003e\n\u003cth\u003eApprox. tank volume supported\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1.9 L Box\u003c\/td\u003e\n\u003ctd\u003e1.9 L\u003c\/td\u003e\n\u003ctd\u003e~950 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3.8 L Box\u003c\/td\u003e\n\u003ctd\u003e3.8 L\u003c\/td\u003e\n\u003ctd\u003e~1,900 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e18.9 L Bucket\u003c\/td\u003e\n\u003ctd\u003e18.9 L\u003c\/td\u003e\n\u003ctd\u003e~9,450 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e56 L Half-Drum\u003c\/td\u003e\n\u003ctd\u003e56 L\u003c\/td\u003e\n\u003ctd\u003e~28,000 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 L Drum\u003c\/td\u003e\n\u003ctd\u003e100 L\u003c\/td\u003e\n\u003ctd\u003e~50,000 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eThese are guide figures for a typically stocked tank, not a hard ceiling — a lightly stocked system will comfortably run on less, and a heavily stocked one benefits from sitting toward the next size up.\u003c\/p\u003e\u003ch3\u003eWhich size do I need?\u003c\/h3\u003e\u003cp\u003eMatch the pack to your system volume against the table above, then round up if your tank is heavily stocked or you're running the media as your only biological stage.

Standard freight applies to the box and bucket sizes; the 56 L half-drum and 100 L drum are bulky items and may attract an oversize freight surcharge at checkout.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003ch4\u003eCan I mix MarinePure Spheres with my existing bio-balls or ceramic rings?\u003c\/h4\u003e\u003cp\u003eYes. MarinePure can be added alongside existing biomedia — there's no compatibility issue — though replacing the older media over time makes better use of your filter's volume.\u003c\/p\u003e\u003ch4\u003eDo I need to cycle the tank again after adding MarinePure?\u003c\/h4\u003e\u003cp\u003eNo, provided you're adding it to an already-cycled system. The spheres will pick up bacterial colonisation from the existing water within days rather than starting from zero.\u003c\/p\u003e\u003ch4\u003eWill MarinePure lower my nitrate on its own?\u003c\/h4\u003e\u003cp\u003eIt helps. The low-oxygen zones deep inside each sphere support denitrifying bacteria, but nitrate control also depends on stocking, feeding and water changes — MarinePure is one part of the picture, not a standalone fix.\u003c\/p\u003e\u003ch4\u003eCan I use MarinePure in a sump without a container?\u003c\/h4\u003e\u003cp\u003eYes, it can be poured loose into a sump baffle chamber, but a MarinePure Vault or a mesh bag makes it far easier to remove for its occasional rinse.\u003c\/p\u003e\u003ch4\u003eIs MarinePure reef safe?\u003c\/h4\u003e\u003cp\u003eYes. It's an inert fired ceramic with nothing to leach, and is used in both freshwater and marine systems including reef tanks.\u003c\/p\u003e","brand":"MarinePure","offers":[{"title":"1.9L Box","offer_id":54773874295075,"sku":"100892","price":95.95,"currency_code":"AUD","in_stock":false},{"title":"3.8L Box","offer_id":55335328121123,"sku":"100893","price":173.95,"currency_code":"AUD","in_stock":false},{"title":"18.9L Bucket","offer_id":55335328153891,"sku":"102688","price":593.95,"currency_code":"AUD","in_stock":false},{"title":"56L Half-Drum","offer_id":55335328186659,"sku":"102666","price":1723.95,"currency_code":"AUD","in_stock":false},{"title":"100L Drum","offer_id":55335328219427,"sku":"100896","price":2800.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/100892.jpg?v=1782705645","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/marinepure-spheres","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
