The main function of Basic Copper Sulphate is that copper ions combine with protein to form a chelate, which denatures and precipitates protein, and inactivates enzymes in insects, thereby killing insects. Since copper sulfate is a weak base and a strong acid, the pH of the salt (5% aqueous solution) is 3.8, and the effect after use is greatly affected by the pH of the water. When the pH value is high, copper ions are easier to precipitate and the effect becomes worse. For acidic water bodies, the content of copper sulfate should be reduced.
If the fish is poisoned by copper sulfate, obviously organic acids should not be used to eliminate the poison. Of course, some aging water bodies have many impurities, active bacteria, and tend to show acidity. These organic impurities can easily offset the influence of copper ions. At this time, it is difficult to judge the amount of copper sulfate. Also pay attention to the amount of zinc oxide and zinc sulfate.
The important reason why we do not advocate the use of copper sulfate is that the safe concentration range of copper sulfate is very small, and the efficacy of the drug is greatly affected by environmental factors. It happens when the drug is damaged during use or the effect is not obvious after the use of the drug. The main factors affecting the toxicity and safe concentration of copper sulfate are: pool water temperature, hardness, pH and organic content.
Under normal circumstances, the higher the water temperature, the more toxic the copper sulfate, and the lower the safe concentration. For example, 0.5 g/m3 of copper sulfate is sufficient to kill mouthworms in summer, while 1.4 g/m3 is effective in winter.
Another reason why Copper Chloride Dihydrate Manufacturers does not advocate is that copper sulfate itself has a certain degree of toxicity. Copper ions are easy to accumulate in organisms, which can easily cause kidney necrosis, decreased hematopoietic function of fish, and decreased intestinal digestive enzyme activity, causing digestive system diseases and affecting the growth of fish, and may even directly lead to death. Zinc sulfate heptahydrate is different.
