Generally, copper sulfate crystals should be used at 5 pounds per acre of pond. So, for instance, if you have a 1-acre pond, you should dissolve 5 pounds of crystals in three gallons of hot water first. For best results, treat your pond using the spraying method to kill the actively growing algae at the top and bottom.
How do you apply copper sulfate crystals to a pond?
You would mix 5 pounds of granular copper sulfate with 3 gallons of hot water, then spray it over half of your pond, wait a few days, and spray the other half. Never treat the entire lake or pond at once, as doing so will deplete oxygen levels while vegetation and algae decomposes after dying.
Can you swim in a pond treated with copper sulfate?
When organisms such as algae become a problem in private or commercial fish ponds, copper sulfate treatment provides an inexpensive solution. However, improper application of copper sulfate can create more problems than it solves.
What is the ratio of copper sulfate to water?
For example, if heating some hydrated copper (II) sulfate gave off 0.060 moles of water, and left behind 0.012 moles of anhydrous copper (II) sulfate (CuSO4), then the ratio is 5:1, and the formula would be written as CuSO4•5H2O.
Can you eat fish from a pond treated with copper sulfate?

It can take as little as two or three days to clear out the line. However, if your system has a slower flow of water, it can take a bit longer (up to a week) to get rid of the roots. By contrast, copper sulfate takes up to four weeks to even start the process of root decay.

What does copper sulfate do to roots?
