No-mess option
Water-soluble packets
Toss packets into several locations. Two 6 oz packets typically cover one surface acre at 4 to 6 ft deep.
Best fit: simple application, small crews, and repeat maintenance.
Pond dye field guide
Pond dye is a concentrated, water-soluble colorant used to tint ponds and lakes. It gives the water a deliberate blue, blue-black, or mirror-black appearance while reducing the amount of sunlight that moves through the water column. It works best as one part of a planned maintenance program.
What pond dye can do
Dye can improve appearance and limit light penetration. It may make conditions less favorable for some submerged plant and algae growth, especially when applied before growth is established. Dye does not kill an existing bloom, remove nutrients, add oxygen, settle suspended clay, or replace a diagnosis.
Choose the water color
Straight blue for a bright, classic pond color that contrasts with green landscaping.
A blue and black blend for a deeper midnight-blue or twilight-blue appearance.
Mirror black for a dark reflective surface that emphasizes sky, trees, and surrounding landscape.

No-mess option
Toss packets into several locations. Two 6 oz packets typically cover one surface acre at 4 to 6 ft deep.
Best fit: simple application, small crews, and repeat maintenance.
Flexible dosing
One quart typically covers one surface acre at 4 to 6 ft deep, or about four acre-feet of water.
Best fit: measured spot dosing and smaller water bodies.
Large-water value
One gallon typically covers four surface acres at 4 to 6 ft deep, or about 16 acre-feet of water.
Best fit: larger ponds, lakes, lagoons, and professional programs.
Two functions
A premixed straight-blue dye and beneficial-bacteria product, generally applied at one gallon per surface acre.
Best fit: programs that call for both tint and biological maintenance.
Good uses
Know the limits
Before you apply
Estimate surface acres and average depth. Acre-feet equal surface acres multiplied by average depth in feet.
Choose the color and format based on appearance, access, water movement, and storage needs.
Distribute liquid in several locations or toss packets across the water so circulation can spread the color.
Reapply when color fades after sunlight, dilution, rainfall, or outflow. Record each application.
