Minimize light penetration and excess nutrients for beautiful water features. Dual-action colorant and enzyme formulation enhances pond aesthetics, blocks out specific light rays and aids in the breakdown of organic waste for a healthy aquatic environment. Once diluted, this non-staining colorant turns water an appealing color and will not stain birds, fish or most concrete fountains or pond rocks. Bio-Blue is specially formulated to safely color lakes, decorative ponds, fountains, and water features a gorgeous shade of blue.
Apply directly or spray evenly over pond surface. 1 gallon treats a surface acre 4-6 ft deep and will mix completely in hours. 1 oz treats 500 gallons. Due to differences in water quality and chemical composition, actual color will differ.
