We use tea cakes to clean the pond, which shows that there are redundant aquatic products that can kill wild aquatic products, such as miscellaneous fish and loach, and that thing is saponin. The yield of Gleditsia sinensis has little to do with the weather, but the growth rate of Gleditsia sinensis is obviously faster than that of normal rainy and low temperature in high temperature and sunny days. The effect will be better in cleaning the pond and removing impurities, so we suggest that it is best to put it in high temperature and sunny days.
Try to lower the water level of the pond to about 50 cm when you put it in. An acre of pond depends on the number of miscellaneous fish. If there are more, it is recommended to use tea cakes 10 kg or more per mu. Before throwing, make tea cakes with a small amount of water, and then sprinkle them evenly into the pool. In two or three days, when a large number of dead miscellaneous fish appear on the surface of the pond, it is best to salvage them to avoid rot and damage the water quality.
