It builds up anaerobic bacterial populations inside denitrators and the anoxic zones of live rock and deep sand beds, and the manufacturer states it is formulated not to fix sulphur, which helps keep hydrogen sulphide production down compared with some sugar or alcohol-fed denitrators.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDenitrifying focus\u003c\/strong\u003e — targets nitrate reduction specifically, rather than general waste processing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-sulfur-fixing\u003c\/strong\u003e — the manufacturer states this formulation helps limit hydrogen sulphide build-up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks with denitrators\u003c\/strong\u003e — can be dosed into a new denitrator alongside a carbon source to help establish it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-pathogenic\u003c\/strong\u003e — no disease-causing organisms, per the manufacturer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIngredients\u003c\/h3\u003e\n\u003cp\u003eContinuum Aquatics declares BacterGen•MD as containing a blend of anaerobic, non-pathogenic marine bacteria selected for denitration.
