MICROBE-LIFT / Nite-Out II is specially designed for the reduction of ammonia and nitrites in the marine and freshwater aquarium. The cultures contained in MICROBE-LIFT / Nite-Out II will establish, promote or stabilize and maintain nitrification in aquarium water, eliminating the toxic effect of ammonia. The nitrifying bacteria in MICROBE-LIFT / Nite-Out II are strains of Nitrosomonas, Nitrospira and Nitrobacter. Nitrosomonas oxidize ammonia to nitrites and Nitrobacter and Nitrospira oxidize nitrites to nitrates.
