Product Q&A

Answer:

Crystal Blue Copper Sulfate is a granule algaecide that is applied directly to the water. You should not try to dilute this product and spray it. The granules are used at rates from 0.68 - 5.4 pounds per acre foot of water, depending on the target algae and how heavy the infestation is. Please refer to the product label for complete instructions.

There is a liquid concentrate copper algaecide called Cutrine Plus that you can use if you need to spray algal mats on your pond.
