Microbe-Lift Nite-Out II Nitrifying Aquarium BacteriaDesigned specifically for aquarium environments that contain marine life. Its highly-specialized microbial consortium of nitrifying cultures are specially formulated to eliminate ammonia via a natural biological process termed nitrification. The cultures contained in Nite-Out II will establish, promote or stabilize and maintain nitrification in aquarium waters, eliminating the toxic effect of ammonia. Liquid nitrifying bacteria contains select strains of Nitrosomonas sp, Nitrospira sp. and Nitrobacter sp. Nitrosomonas oxidize ammonia to nitrite and Nitrobacter and Nitrospira oxidize nitrite to nitrate. Microbe-Lift Night-Out II comprises select microorganisms that are autotrophic - able to use carbon dioxide as the sole source of carbon - and are relatively slow growing, requiring specific conditions for optimum growth with typical cell division rates from 8 to 16 hours. Their performance and rate of growth is impacted by the environmental parameters required for nitrification.
