Airmax Black DyeMond Pond Dye for Large Ponds & Lakes, Fish-Safe Concentrated Liquid Water Colorant, 1 Quart 

Pond dye is a liquid coloring agent designed to enhance the beauty of your pond, provide a natural pond shade, and improve water quality. The most popular reason to add dye to your outdoor pond is to enhance the natural color and beautify your landscape. Pond dye colors include blue, dark blue, blueish green, aqua or ocean blue, twilight blue, midnight blue, and black. All dyes, also called tints, protect and shade the pond the same way. Choose the tint you prefer. While dye is great for aesthetics, pond dye also limits sun exposure, protects fish, and promotes a balanced ecosystem in your large pond or lake. Excessive sunlight promotes overgrowth of submerged aquatic plants, weeds, and algae. Pond dye blocks specific portions of the sunlight spectrum, slowing growth and keeping your water crystal clear and clean.
