GreenClean Liquid Blue Colorant
Enhance Your Water’s Health, Quality, and Appearance.
GreenClean Liquid Blue Colorant is one of the simplest ways to help reduce problems associated with algae in your pond. The deep blue colorant prevents the sun’s UV rays from penetrating the water column, thereby inhibiting photosynthesis (growth) of all types of algae and cyanobacteria.

Use GreenClean Liquid Blue Colorant in conjunction with beneficial pond bacteria to maintain a clean, clear, and healthy pond all year long. GreenClean Liquid Blue Colorant comes in one quart containers.

- Non-Toxic and Non-Staining
