Will Bluestone kill fish?

Asked by: Linda Marinov

Does copper sulfate kill fish?

Decay of plant material uses scarce dissolved oxygen, leading to fish suffocation. Fish treated with copper sulfate at approved rates are safe for human consumption with zero withdrawal time. Fish kills due to direct toxicity of copper sulfate happen occasionally.

How do you use bluestone?

Bluestone is durable, attractive, and ideal for all kinds of uses including patios, pool decks, stone steps, or entryways. Both types of U.S. bluestone have long been used as pavers in hardscapes.

How do I get rid of algae in my pond without harming fish?

You can use a pond or garden rake to remove as much surface algae as possible. If your pond is too large, begin by using a chemical algaecide. There are a number of quality algaecides available that will provide almost immediate relief for an out-of-control algae situation when properly applied to your pond.

Is copper sulfate safe for ponds?

Copper sulfate can be toxic to fish and other organisms. Copper sulfate results in copper build up in pond sediments and creates a sterile bottom in the pond. Besides many important organisms, it kills beneficial bacteria.

How long does copper sulfate take to kill fish?

about 48 hours

Liquid copper sulfate is best applied by using a broadcast sprayer. Within about 48 hours after application, the algae should be brown and dead or dying.

Can you eat fish from a pond treated with copper sulfate?

There are no restrictions on swimming, eating fish from treated water bodies, human drinking water, pet/livestock drinking water, or irrigation. Copper is an element, and so is not broken down like other herbicides.

Is blue stone poisonous?

Blue stone (neela thotha, in local terms) is dehydrated copper sulfate and is commonly used as a pesticide, in the leather industry, and in homemade glue. It results in a rare form of poisoning limited to the Asian continent, with a high incidence in India and Sri Lanka prior to the 1980s.

Is blue stone blue?

Bluestone is a fine-grained sandstone from Pennsylvania and New York, characterized by its grey-blue color—but it’s not always blue. “There are so many color variations,” explained Bill Mirch, Vice President of Tompkins Bluestone.

Is copper sulphate harmful to humans?

Copper sulfate can cause severe eye irritation. Eating large amounts of copper sulfate can lead to nausea, vomiting, and damage to body tissues, blood cells, the liver, and kidneys. With extreme exposures, shock and death can occur.

What happens when you put copper sulfate in 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.

Is copper good for grass?

Yes, at relatively low concentrations, copper sulfate can kill grass. For example, adding 1 oz of copper sulfate to 1 gallon of water and spraying it over an area of about 250 square feet can kill moss and algae while sparing a lawn.

Is it safe to swim in water treated with copper sulfate?

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.

How do I add copper sulfate to my pond?

Typically, use 1 gallon of liquid copper sulfate diluted in 10 gallons of water per one surface acre of your pond. Then, apply the liquid copper sulfate for algae control in ponds using a broadcast sprayer. Make sure to check the label before buying a liquid copper sulfate.

What does copper sulfate do for a pond?

Copper Sulfate is a granulated algaecide great for treatment of pond and lake algae and is also suited for treating areas to eliminate swimmer’s itch. Copper Sulfate Algaecide is an effective algae control product that also helps relieve Swimmer’s Itch and leech issues.

How long does it take for copper sulfate to work in a pond?

The treatment will likely cause a sudden, algal die-off causing an oxygen depletion that could result and the dead algae decay and the fish will suffocate. Treating only one third of an area at over 48-72 hours will help avoid crashing your oxygen levels.

How often should I use copper sulfate?

Application by Slug Method: Make a dump of Copper Sulfate into the irrigation ditch or lateral at ¼ to 2 pounds per second of water per treatment. Repeat about every 2 weeks as needed. A dump is usually necessary every 5 to 30 miles depending on water hardness, alkalinity, and algae concentration.

Can you buy copper sulfate?

Stores That Sell Copper Sulfate

I found copper sulfate at Home Depot as Zep Root Killer, which is labeled as copper sulfate pentahydrate and is sold with septic tank and drain cleaning chemicals (not with other garden root killers or with other plumbing chemicals).
