Microbe-Lift Nite-Out II is specially Formulated for Rapid Ammonia and Nitrite Reduction in fresh and slat water aquaria. Microbe-Lift Nite-Out II is designed specifically for aquarium waters 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 contain in Microbe-Lift Nite-Out II will establish, promote or stabilize and maintain nitrification in aquarium waters, eliminating the toxic effect of ammonia. Microbe-Lift Nite-Out II liquid nitrifying bacteria contains select strains of Nitrosomonas, Nitrospira and Nitrobacter. Nitrosomonas oxidize ammonia to nitrite and Nitrobacter and Nitrospira oxidize nitrite to nitrate. Microbe-Lift Nite-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
