Pond dyes are completely safe for people, fish, pets, plants, and birds.
CrystalClear PondTint is a non-toxic pond dye colourant designed to help keep the water sparkling clean and cool. Shaded pond water naturally stays clearer than pond water in full sun. If a pond does not have significant surface plant coverage, it is a good idea to use PondTint in the hot summer months to shade the pond. Pond dye gives shaded ponds a rich look and turns a brown or gray water feature into a stunning pool that reflects the trees and landscape.
When added to your pond, pond dye will spread throughout the water column within a few hours to form a safe, protective barrier to keep water shaded from the sun as well as enhancing depth and contrast.
