Aqua Shade Pond Dye-2.5 Gal

A lake dye registered by E.P.A. for control of aquatic plant growth. Aquashade is a unique blend of blue and yellow dyes specifically designed to screen or shade portions of the sunlight spectrum required by underwater plant and algae growth. This shading inhibits photosynthesis in young, bottom growth suppressing growth and development of nuisance conditions. For best results, apply before growing season starts, or when growth is on the bottom. Application rate: 1 gallon per 4 acre feet of water.
