Contrary to popular belief, there's more to dye than adding beauty to your lake or pond. While also being a beautiful blue, dye can prevent fish predation from wading birds, such as Blue Heron, that pray on spawning game fish and Koi. So, if you're struggling with protecting your fish from predators, or find the color of your pond or lake not to your desire, pond or lake dye might be the right choice for you.
What are the dye options?
There are three liquid/packet dye colors:
Standard blue dye: Creates "Caribbean" blue water
Black dye: Creates a more reflective surface appearance that can give the illusion of a deeper pond
Serenity dye: A mixture of blue and black
Dye packets: For easy application, pond dye water-soluable powder packets are as simple to use as tossing one into the pond. You later remove the packets once they've dissolved, which takes around 2 minutes. If there is wind, you will want to toss the packet in up wind so it will drift across the pond to dissolve.
When do I apply the dye?
With all dyes, it is best to apply early in the season, March or April, for best results. Application is a simple process; just pour the dye into the water at two or three different locations. The dye naturally diffuses throughout the water without the need of a sprayer or spreading of the applicaiton. ALWAYS reference the label for proper application directions.
How long does the dye last?
Pond dye lasts any where from 4 months to a week due to a variety of factors including the flow of water through the pond/lake to the amount of rainfall.
Are there any safety precautions?
Always use caution! Use gloves and protective clothing if possible, clothing you wouldn't mind getting a little messy, because undiluted dyes will stain both skin and clothing.
Water from dyed ponds can be used for irrigation of crops, watering livestock or pets, and swimming once the dye is dispersed. The dyes are both nontoxic and harmless to fish, so after using dye your fish would still be safe to eat.
Does dye inhibit aquatic plants?
EPA registered dyes can be used in order to reduce or inhibit the growth of aquatic plants by restricting sunlight into the pond and inhibiting photosynthesis in young bottom growing plants.
Water exchange rate associated with a lake or pond could be a major limitation in the use of aquatic dyes. If there is substantial watershed, ponds or lakes could receive considerable flow during rain events and fail to maintain their color.
