Concentrated Blue Pond Dye by the Scott Aerator Company is now available in water-soluble packets. Simply toss the packets directly into the pond. No measuring or mixing is required. They dissolve within minutes to provide a pleasing “natural blue” color. This product will not harm or stain birds, fish, plants, pets or wildlife. Its non-toxic formulation is compatible with most aquatic herbicides and algaecides. Each container contains three packets, enough for a one-acre pond at six feet deep. Made in the USA.
