Decreases Ammonia & Nitrite Toxicity For SALT & FRESH WATER Contains: Nitrosomonas, Nitrospira and Nitrobactor 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 with typical cell divisions rates from 8 to 16 hours. Their performance and rate growth is impacted by the environmental parameters required for nitrification.
