The Microbe-Lift Ammonia Remover immediately eliminates chlorine, chloramines and high levels of ammonia by turning it into non-toxic ammonium for your filter to remove, without altering your aquariums alkalinity, pH or biological filtration. This formula is not intended to use with other permanganate or chlorite-based treatments or tested with Nessler's total ammonia test kits; rather salicylate-based (indole-phenol) tests should be used instead. This will treat up to 960 gallons of aquarium water.
