This concentrated black lake dye has been formulated to treat larger ponds & lakes. Each super-concentrated quart will treat an entire surface acre of pond water, up to 3-6 feet deep (approximately 1-2 million gallons). It creates a more natural dark color to the pond water. It will not stain birds, fish, plants, pets, or wildlife when applied at the recommended rate. It is non-toxic and is compatible with most aquatic herbicides and algaecides. It can be mixed quickly and evenly throughout the pond with the use of a fountain, aerator or similar mechanical device.
For best results, this product should be used with beneficial pond bacteria to help ensure your pond or lake remains clean and clear all season long.
