MICROBE-LIFT / Nite-Out II is designed specifically for aquarium waters that contain marine life. Its highly specialized microbial consortium of nitrifying cultures is specially formulated to eliminate ammonia through a natural biological process called nitrification. The cultures contained in the MICROBE-LIFT / Nite-Out II will establish, promote or stabilize and maintain nitrification in the aquarium waters, eliminating the toxic effect of ammonia. The liquid nitrifying bacteria MICROBE-LIFT / Nite-Out II contains selected strains of Nitrosomonas, Nitrobacter and Nitrospira. Nitrosomonas oxidize ammonia to nitrite and Nitrobacter and Nitrospira oxidize nitrite to nitrate.
