Item Information

Crystal Blue Copper Sulfate Pond Algae Control- 15LB

  • Copper sulfate should be used as a pond algae treatment on actively growing algae in water temperature above 60F
  • When getting rid of algae in a pond, it is always important to treat 1/2 of the pond algae at a time to avoid killing too much algae and depleting the water of oxygen
  • Granular copper can be applied in one of three different ways: broadcast crystals, place crystals in a burlap bag and drag behind boat, or dissolve crystals and spray.
  • The application method we recommend is to dissolve the crystals in hot water and spray actively growing algae.
  • Do Not use this product with Koi, Goldfish, or Trout
  • 2lbs treats approximately 15,000 sq feet. Always be sure to read the product label before application

Dogs play in pond. How long after treatment must I keep them away?

Asked by: Scott7588
Please see the response from the manufacturer below: For our AB Brand Copper Sulfate Crystals, # 390835A, there are no general restrictions for swimming or domestic animals drinking the water. You will want to keep the dogs away while applying but once the product is in the water, dissolved or diluted, you can use the pond.

Would this control the cattails around a pond and not hurt the fish in it?

Asked by: Southtexan
Copper sulfate crystals are used to control different types of algae, not cattails. To control cattails you would need to use a glyphosate based product (that kills to the root). We recommend using our Crystal Blue Cattplex (SKU1049009). Glyphosate will not hurt the fish if you follow the dosing instructions.

How long does it take before results?

Asked by: Wrisley
Copper sulfate provides results within 24-48 hrs. Any longer they should use Cutrine Plus due to water hardness.
