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

Crystal Blue Copper Sulfate Crystals, 222 is rated 4.5 out of 5 by 48.
Rated 5 out of 5 by from Best Solution for Algae in our stock tank The algae in our tank had started to completely take over. I've tried a million different products to get rid of it and had some luck, BUT this is AWESOME! I broadcast it directly onto the algae and within a day or 2, there was a noticeable difference. I only did 1/2 of the tank the first time and followed up with a second treatment about 7 days later for the other 1/2 and the algae is completely gone. Well worth the purchase price!

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.

Can I use Copper Sulfate Cryrstals to kill moss in my grass?

Asked by: Al0071692145
You may use copper sulfate to kill moss- however if you are spraying directly on your grass it will burn it back.

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.

Can this product benused in a livestock tank

Asked by: Doug753
This product is not labeled for use in livestock tanks. While copper is safe for livestock, this product is so concentrated there is no dosing breakdown we can give you for use in such a small volume of water.
