Applied BioChemist - Aqua Shade - 1 gal

Use Aquashade in natural and manmade ponds, lakes and fountains to turn the water a pleasing aqua-blue color. This not only enhances the appearance of the water but also shades the water to prevent plant and algae growth. This water treatment chemical has a blend of blue and yellow dyes that effectively inhibits photosynthesis in young, bottom growth and may prevent development altogether if applied early enough in the season.
