  • Blocks Sunlight To Prevent Weed Growth
  • One Gallon Treats Up To 1 Acre
  • Shades Your Pond An Aqua-Blue Color

Aquashade® Pond Dye is a blend of blue and yellow dyes which shades specific portions of the sunlight spectrum (red-orange and blue-violet) required by underwater aquatic plant and algae growth. This aqua blue pond dye creates shading that inhibits photosynthesis in young, bottom growth and may prevent development altogether if the pond color is maintained throughout the early season. Aquashade®; is primarily effective in water deeper than two feet, floating plants such as lilies are unaffected by this product if they have already reached the surface. Water treated with Aquashade® aqua blue pond dye will retain a light aqua-blue tint following application. One gallon treats up to 1 acre, 4-6 feet deep.

Use the lower (0.5-0.8 ppm) rates early for suppression of submersed plants (Leafy Pondweed, Chara, Slender Naiad, Watermilfoil, Hydrilla) and Filamentous Green (Spirogyra sp.) and Bluegreen algae growing at depths greater than 2 feet of the surface. Use higher rates (1.5- 2.0 ppm) in shallow waters or in-season where growth is within 2 feet of surface.

How To Apply

Measure out required amount of Aquashade® into a pourable container or apply directly from the product container by pouring around shoreline water and/or in offshore areas from a boat. Aquashade® will mix throughout the water on its own, however, more widespread application or aeration devices/fountains will provide quicker dispersion. In freezing climates, Aquashade® may be poured onto the ICE in a 3 foot (1 meter) diameter circle it will melt a hole and disperse underneath. (Be certain ice conditions are safe before making application.)

When To Apply

For best results, apply Aquashade® as a pre-emergent (prior to plant germination) before the growing season. Aquashade® may even be applied directly onto ice cover, (where applicable). Use during the growing season will suppress the rate and extent of underwater growth, but may not eliminate it. Aquashade® has reduced effectiveness in waters less than 2 feet deep and on matured submersed aquatic plants. It does not control floating algae mats, free floating plants, or emergent (shoreline) vegetation. These plants can be physically removed or treated with an appropriate EPA registered aquatic herbicide or algaecide if more complete control is desired. When using algaecides or aquatic herbicides, always follow label restrictions, precautions and directions for use.


Allow at least one hour for Aquashade® to disperse throughout the water body before using water for swimming, irrigation or livestock watering or avoid pouring concentrate within 50 ft. of these intake/use areas, allowing dye to self-disperse into them.
