Aquashade® Aquatic Plant Growth Control

This is more than a colorant. It is a precise blend of blue and yellow dyes that shade specific portions of the sunlight spectrum (red-orange and blue-violet) required by underwater aquatic plant and algae growth. This shading inhibits photosynthesis in young bottom growth and may prevent development altogether if the color is maintained throughout the early season.

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.
Use in conjunction with herbicides or algaecides for control of surface algae mats or shallow-water plants. 

Not for use in drinking water. No restrictions for animal/livestock drinking, irrigation, swimming or fish consumption when used at label rates.*
