Aquashade contains a blend of blue and yellow dyes designed to absorb specific wavelengths of light critical to plant photosynthesis. Treated water will retain a light aqua-blue tint following application. For best results, apply Aquashade as a pre-emergent (prior to plant germination) before the growing season. For use in natural and manmade contained lakes and ponds (ornamental, recreational, fish bearing & fish farming bodies) with little or no outflow of water. Aquashade controls:
