While able to survive in virtually any environment, PSNB are "in their element" where there is little-to-no oxygen, at least some light and plentiful organic matter (deep sand beds, under live rock, within porous filter media, etc.). This makes them very much unlike "traditional" nitrifying bacteria which prefer dark, highly aerated environments and utilize only inorganic carbon sources (e.g. CO2). Thus, rather than competing with the nitrifiers found in typical biofilters, the PNS bacteria in Hydrospace™ PNS Substrate Sauce™ actually complement them. In so doing, they reduce the amount of time required to complete the nitrogen cycle in new aquaria! Additionally, unlike the aerobic nitrifiers, PNS bacteria can perform denitrification, converting nitrate into harmless nitrogen gas.
PNS Substrate Sauce™ is a live culture of two ecologically important PNS bacteria. Formulated to promote rapid cycling in marine aquaria!
