Cautions in the Use of Copper Sulfate
1. The toxicity of copper sulfate is proportional to the water temperature, so it should be used in the morning on sunny day, and the dosage should be reduced according to the water temperature.
2. The amount of copper sulfate is directly proportional to water fertility, organic matter and suspended matter content, salinity and PH value. Therefore, the appropriate amount of copper sulfate should be selected according to the specific conditions of the pond.
3. When the water is alkaline, copper sulfate should be used carefully to avoid the formation of copper oxide to poison fish.
4. The safe concentration range of copper sulfate for aquatic animals such as fish is small and its toxicity is high (especially for fry). Therefore, the dosage of copper sulfate should be calculated accurately when it is used.
5. When dissolving, do not use metal utensils, do not use water above 60 degrees Celsius, in order to prevent the loss of efficacy, after medication should be fully oxygenated to prevent dead algae from consuming oxygen, affecting water quality, leading to flooding ponds.
6. Copper sulfate has some toxic and side effects (such as hematopoietic function, feeding and growth) and residual accumulation, so it can not be used frequently.
7. Copper sulfate should not be used in the treatment of cucurbits and powdery mildew.
