Where this does not exist, it is necessary to create such an environment, and this is where the sulfur denitrators come in to play.\u003c\/p\u003e\n\u003cp\u003eNeither bio-pellets nor traditional nitrate reactors (alcohol) are maintenance free and without consequence. It’s their inadequacies that have led to the popularity of sulfur based de-nitrates.\u003c\/p\u003e\n\u003cp\u003eSulphur nitrate reactors implement a process called \u003cem\u003e\u003cstrong\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/22432298\"\u003eautotrophic sulfur denitrification\u003c\/a\u003e\u003c\/strong\u003e\u003c\/em\u003e. This process has been used to remove excess nitrate from fresh drinking water for over 15 years. Bacteria (such as \u003cem\u003eThiobacillus denitrificans\u003c\/em\u003e and \u003cem\u003eThiomicrospira denitrificans)\u003c\/em\u003e inhabit the reactor, under anoxic conditions. Here they oxidize reduced sulfur to sulfate, while reducing nitrate to liberate the oxygen for their own use. The bacteria uses residual co2 within the water as their carbon source, so they don’t need constant dosing. \u003c\/p\u003e\n\u003cp\u003eLike any filtration method that uses bacteria, sulfur nitrate reactors require cycling. The time span for proper functioning can be rather long. After the running-in period, maintenance (apart form checking the exact water flow) is simple. Once cycled, sulfur reactors may the most effective method of nitrate removal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdvantages of Sulfur Denitrification:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSimple to set-up\u003c\/li\u003e\n\u003cli\u003eNeeds no additional feeding with carbon based foods\u003c\/li\u003e\n\u003cli\u003eProtein Skimmer not required\u003c\/li\u003e\n\u003cli\u003eLong lasting: Sulfur media lasts up to 2-3 years\u003c\/li\u003e\n\u003cli\u003eUnits can be easily refilled or serviced\u003c\/li\u003e\n\u003cli\u003eCan be used in freshwater or saltwater aquariums\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe water coming out of the Deltec Sulfur Nitrate Filter will have a low pH value and should be lead through a container with ROWAlith C or similar. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNOT INCLUDED:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eDosing\/Peristaltic Pump\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e\u003cspan\u003eSulfur\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eMedia\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Deltec","offers":[{"title":"Default Title","offer_id":42598030442650,"sku":"NF90","price":629.99,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/5215\/9130\/files\/Deltec_NF90.webp?v=1777930245","url":"https:\/\/aquariumdepot.ca\/products\/deltec-sulfur-reactor-denitrator-nf90","provider":"Aquarium Depot","version":"1.0","type":"link"}
