Pond & Lake Q & A

Q: How do you turn a one acre pond blue in color? My wife has fish in it and wants the blue tint? – Scott of Mississippi

A: Turning your pond a blue color is a great way to not only to provide your pond with a beautiful blue shade, but also will reduce the amount of sunlight that penetrates through the pond. Surprisingly enough, just one quart of Nature’s Blue Pond Dye will shade a one acre pond (43,560 sq. ft.) with an average depth of 4′-6′. I would use one quart, wait 24 hours and evaluate. If you would like a deeper color add another 1/2 quart. Also, with Nature’s Blue Pond Dye, there are no water use restrictions and it is safe for fish, birds, pets, horses, livestock and wildlife.

If you are more into beautiful reflections and a richer tone instead of the blue shade, I would recommend Black DyeMond Pond Dye.

  1. Our natural pond has alot of tannin in the water. I wonder if either of these would improve the color?

  2. We have been using your products now for about 3 years and what a difference in our pond. I started out using your Blue Pond Dye but I’m now using a combination of the Blue and Black DyeMond Dye. I am assuming that the darker the water is, the less light that can penetrate in to allow weed growth. Am I correct in this assumption, or do both colors have the same light filtering properties?

  3. I live in Buffalo New York area, its been a very cold winter. The ice has defrosted off my pond and low and behold I have green hairy algea growing on all the rocks in the pond. Its a fairly small pond (10×8), with quit a few goldfish, many are pretty large. I don’t have the waterfall running yet. Is there anything I can do to stop the green hair from taking over further?

  4. Cheryl,

    If your pond has a lot of tannins in it, do you happen to have an abundance of leaves or twigs that fall into the pond? Limiting those, if possible, would help with the color.

    Also, as for the Nature’s Blue Pond Dye or Black DyeMond Pond Dye. I would try the black if your pond has those brownish tannins in it. Blue and Brown usually won’t go well together in that situation. Hope this helps!

  5. Sue LeCalsey,

    I’m glad to here you are getting great results from our products!

    As for your question, Both blue and black dyes will have the same sunlight filtering properties. It really comes down to a point of preference or like in Cheryl’s case, one color just may be a better option. Your right, in a sense, the more you use the darker the color, thus the longer the sunlight penetration will be restricted, but just know that using the recommended dosage rate on the bottle will get you to where you need to be.

    Thanks for the comment!

  6. Sharon,

    One product that is great at lifting algae off of rocks is called Oxy-Lift Defense. Although it won’t kill algae, it will quickly and easily lift it from the rocks.

    Sharon, one thing to remember when reading my last post about Combating String Algae, is that if you have an abundant fish load, you have to compensate with more filtration, aquatic plants or natural bacteria to help bring your pond back into balance. Depending on your fish load, I would make sure your filtration system is built to handle your fish load and make sure you add some Water Hyacinth or Water Lettuce if possible. These aquatic plants are great at competing for the same food source as algae. Also, read more about the DefensePAC here.

    Hopefully this helps!
