Concentrated blue pond dye is designed for use in water gardens and koi ponds.
Directions for Use
Apply one 1 fl. oz. per 1000 gallons of pond water every month or as needed. To prevent staining, handle with care prior to dilution and dispersing in water. Use of gloves is recommended while applying product. Dye will not stain rocks, plants, pets, wildlife or people when dispersed and diluted in pond water. Chlorinated water will cause color to fade, requiring more frequent application.
