When used as directed, KoiZyme will reduce the bacterial count of Aeromonas, Pseudomonas and other pathogenic bacteria to such low levels that they will not have an effect on koi. KoiZyme will not harm biofilters and has a 4–6 month shelf life (18 months if kept refrigerated). Use weekly at 4 teaspoons per 1,000 gallons. Not FDA-approved.
