Black Dye – Surface Water Shading for Algae

Black Dye is a concentrated, EPA approved, non-toxic water colorant designed to limit sunlight penetration by the use of UV filters in lagoons, ponds, and other wastewater treatment basins. By reducing light availability, Black Dye helps suppress the growth of algae and submerged aquatic weeds, improving the efficiency and appearance of your treatment system.

Safe for use in all types of water treatment environments, this dye blends evenly throughout the water column and provides a long-lasting shading effect without harming wildlife or disrupting system performance. Ideal for aesthetic enhancement and biological control, Black Dye supports better water clarity and operational stability in wastewater facilities.

Available in Individual quart or gallon bottles
