FRITZZYME #9 contains pure, live, active cultures of non-pathogenic, non-toxic Nitrosococcus and Nitrococcus nitrifying bacteria. Proven to be the best saltwater nitrifying bacteria product available in an independent laboratory test performed at The University of California, FRITZZYME #9 begins rapidly reducing ammonia and nitrite when added to any system.

Always add FRITZZYME #9
