BacterGenMD is a breakthrough in microbial cultures and is specifically designed to establish anaerobic bacteria populations in denitrators and anoxic zones (those zones that are depleted in dissolved oxygen), such as internal pores in live rock and to establish anoxic slime layers within all zones, even within zones otherwise saturated with oxygen. BacterGenMD does this by developing layers of bacterial slime to prevent oxygen availability to anaerobic microbes thereby encouraging denitration by conversion of nitrates to nitrogen gas. Whereas most competing products are designed primarily for freshwater aquariums, and most don't do much to address nitrate reduction, BacterGenMD will quickly generate effective anoxic zones and encourage beneficial denitrifying bacterial populations in seawater. Whereas competing products may increase the production of toxic hydrogen sulfide in the system, and denitrators, particularly those utilizing alcohol or sugar for fuel are known for hydrogen sulfide production, BacterGenMD is non-sulfur fixing and will reduce hydrogen sulfide levels.
