EasyPro Pond Products PD16 Blue Pond Dye 16000Gallon

This blue colorant is designed for use in water gardens and koi ponds. It will not stain birds, fish, plants, pets, wildlife or people once diluted and when applied at the recommended rate. Handle with care prior to dilution to prevent blue staining. Eastport' s blue pond dye provides a more aesthetically pleasing appearance to pond water by offering a "natural blue" color. This formulation does not contain yellow dye, so it will not shade the water green.
