Pond dye shades the BOTTOM of your pond to block sunlight from reaching the pond's bottom. Pond dye is not going to dye your fish or other wildlife around your pond. 

When to start applying dye:

For best results, start applying dye in early Spring before aquatic plants and algae begin to grow. Before dye begins to fade, apply more pond dye. 

Why should I use Pond Dye?

Pond Dye is an inexpensive and harmless way to manage pondweeds and algae in ponds.

    This is a great product, it was easy to apply and the color is a natural lake green color. Exactly what I was looking for.

    Before using Pond Logic Twilight Blue Pond Dye our pond had a terrible algae problem and a weed or pond grass problem too. We would spend hours each week trying to clear out the scum and the smell was awful. The water is turned a blueish color and it looks amazing. Since using the dye our pond looks amazing with no algae problem and it has all but eliminated the weed or pond grass infestation.
