Introduction To Cuprous Chloride Effect

  • The main effect of Cuprous Chloride is that copper ions combine with proteins to form a chelate, which denatures and precipitates proteins, and also inactivates the enzymes in the parasites, so it can kill the parasites. Because Cuprous Chloride is a weak base and strong acid The pH value of salt, a 5% aqueous solution is 3.8, and the effect after use is greatly affected by the pH value of the water body. When the pH value is high, copper ions are more likely to precipitate and the effect becomes worse. For acidic water bodies, the amount of Cuprous Chloride should be reduced. If the fish has been poisoned by Cuprous Chloride, obviously organic acids should not be used for detoxification. Of course, some aging water bodies have many impurities, active bacteria, and easy to be acidic. These organic impurities can easily neutralize the effect of copper ions. At this time, it is very difficult to judge the amount of Cuprous Chloride.
    The very important reason why we do not advocate the use of Cuprous Chloride is that the safe concentration range of Cuprous Chloride is very small, and the efficacy of the drug is greatly affected by environmental factors. When the drug damage occurs during use or the effect is not obvious after the drug is used Has happened. The main factors affecting the toxicity and safe concentration of Cuprous Chloride are: pool water temperature, hardness, pH value, organic content, etc.
    In general, the higher the water temperature, the more toxic the Cuprous Chloride is, and the lower the safe concentration. For example, Cuprous Chloride 0.5 g/m3 is sufficient for killing mouthworms in summer, while Cuprous Chloride 1.4 g/m3 is needed in winter. effective.
    The second reason is that 8-hydroxyquinoline Copper is inherently toxic. Copper ions are easy to accumulate in organisms, which can easily cause kidney necrosis, decreased hematopoietic function, lower intestinal digestive enzyme activity, and digestive system disorders. , Affect the growth of fish, and even directly lead to death.
