KoiZyme is a biological formula of naturally occurring bacteria, enzymes and micro nutrients. When KoiZyme is introduced into pond water that is infected with Aeromonas, Pseudomonas or any gram negative or gram positive bacteria, the bacteria and enzymes in KoiZyme competes with these pathogens for the nutrients in the pond water. These nutrients are primarily a nitrogen based nutrient from fish waste. KoiZyme will consume these nutrients and thus starve Aeromonas and Psuedomonas. The bacteria counts (CFU’s) of these pathogens will then be reduced to such a low level that they will not have an affect on your fish.



When used as directed, KoiZyme will reduce the bacterial count of Aeromonas, Pseudomonas and other pathogenetic bacteria to such low levels that they will not be a threat to the health of your fish.

It is impossible to completely remove the Aeromonas and Pseudomonas bacteria from the pond water, but KoiZyme, when used on a regular weekly basis, will keep the Aeromonas, Pseudomonas and other pathogens levels so low, they will not affect the fish.
