Is copper sulfate poisonous to fish?
Studies with several aquatic species have found copper to be highly to very highly toxic to fish and aquatic life. Trout, koi and juvenile fish of several species are known to be particularly sensitive to copper. Fish kills have been reported after copper sulfate applications for algae control in ponds and lakes.
Can you swim in a pond after you put copper sulfate in it?
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.
How do you mix copper sulfate in 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.
How often can you put copper sulfate in a pond?
Remember: Using any form of copper sulfate for algae control in ponds should always be done in two batches. Treat half of your pond first, then wait for at least five days before treating the other half to avoid oxygen depletion.
Is copper sulfate safe to use in swimming pools?
It's generally safe for swimmers, but because copper sulfate doesn't evaporate, it should be used sparingly. High concentrations resulting from repeated use can cause staining of the pool liner, the submerged pool equipment, and possibly the skin of anyone who stays in the water too long.
What is the ratio of copper sulfate to water?
A mole of CuSO4•5H2O contains 5 moles of water (which corresponds to 90 grams of water) as part of its structure. Therefore, the substance CuSO4•5H2O always consists of 90/250 or 36% water by weight.
What can I put in my pond for algae?
To get rid of algae in a pond, try planting more aquatic plants in your pond, like lily pads, cattails, or watercress, which will absorb the nutrients that algae needs to grow. You can also throw a small bale of barley straw into your pond, which will slowly kill any algae over the course of a few weeks while it rots.
Why is copper toxic to aquatic creatures?
In fact, copper is one of the most toxic metals to aquatic organisms and ecosystems. Because copper is an algaecide, it is not surprising that it causes decreased algal growth when inadvertently discharged to a water body.
What does copper sulfate do to water?
As stated above, copper sulfate accumulates as a heavy metal precipitate once it is applied to water. Because of this, it does not biodegrade. A buildup of copper sulfate can lead to a sterile water bottom, which can decrease and kill beneficial bacteria.
What does copper sulfate treat in fish?
Copper sulphate (sulfate) is a chemical used in the treatment of some bacteria, algae, fungus and some fish parasites such as Ich. It can also be used to kill snails, accidentally or on purpose. This chemical is toxic if the wrong dosage is used.
Is copper sulfate safe for catfish?
Copper sulfate pentahydrate (hereafter referred to as copper sulfate) is an important tool for the catfish producer. As an EPA-approved algicide, copper sulfate is often an effective treatment for controlling algae in catfish ponds.
Does copper attract fish?
However, one not-so-well-known secret that has been handed down from generation to generation of anglers is that copper lures just seem to be better at attracting fish that are hiding or feeding in either fresh or salt water.
How do you dilute copper sulfate?
For example, if you need to make 500 ml of dilute copper sulfate solution using a dilution factor of 10, then add (10-1) x 50 ml = 450 ml of water to the solute in the flask. Close the flask with a stopper and shake to mix the contents thoroughly. The result will be an appropriately diluted solution.
Can I use copper pipe in a fish pond?
copper pipe is toxic to fish and will leach copper into water resulting in fish with weakened immune systems ,organ damage or death depending on levels reached . copper is a soft metal and corrodes in contact with acidic (low ph) water .
What is copper sulfate used for in animals?

How do you use copper sulphate in the garden?
What happens if you get copper sulfate on your skin?
