Precautions When Using Cupric Sulfate

2023-09-27 09:33

What is Cupric Sulfate:

Cupric Sulfate (CuSO4), a white or off-white powder, commonly known as bile alum, stone gall, gall alum, blue alum. Its aqueous solution is weakly acidic, showing blue. Cupric Sulfate is an important raw material for the preparation of other copper-containing compounds.


In agricultural and non-agricultural fields, copper sulphate has a wide range of uses and can also be very useful. However, because it is a toxic substance, so there are many things to pay attention to when using it, so what are the precautions when using copper sulfate:

1. Cupric Sulfate is directly proportional to the water temperature: so it is best to use it in the sunny morning to get the best effect, avoiding high temperature, the temperature is not more than 60℃, and reduce the dosage accordingly to the water temperature.

2. The dosage of Cupric Sulfate is directly proportional to the fertility of the water body, the content of organic matter and suspended solids, the salinity, PH value, so in the process of using it, we have to choose the appropriate dosage according to the specific conditions of the pond, the bactericidal ability of Cupric Sulfate decreases with the increase of PH value, the increase of organic matter and the presence of salt.

3. It can treat the external parasitic flagellates, ciliates, trematodes, Chinese fish fleas, etc. It can be used to prevent and control fish diseases caused by protozoa (e.g., ovine flagellosis, cryptoflagellate disease, fish bordatella disease, trichomoniasis, oblique tubeworms, rotifers, etc.) as well as those caused by crustaceans (e.g., Chinese fish flea disease, etc.). However, it can not treat the protozoa and sporozoa that form cysts on the body of aquatic animals, such as melioidosis, the treatment of copper sulfate is not only ineffective, but also will make the melioidosis form cysts and reproduce in large quantities, which will aggravate the condition.

4. Small safety range: Although the use of Cupric Sulfate is very much, but in the use of the human body is a certain danger, it is recommended that the staff should be more careful, should wear a safety mask, dust mask. Never use it if you are not a professional.
