Use of Water Conditioners in Water-Recirculation Systems

Abstract

Commercial water conditioners containing concentrated solutions of Nitrosomonas sp. and Nitrobacter sp. bacteria were evaluated for their effectiveness in activating nitrifying biofilters in hatchery water-reconditioning systems. Conditioners were tested in both fresh- and saltwater situations; the freshwater conditioner did not immediately nitrify ammonia as the saltwater conditioner did.
