The cause of turbidity in the water body:
(1) Weather reasons. In the high-temperature and low-temperature weather that did not occur in 60 years, abnormal weather caused abnormal movement of the crabs and caused the water to become cloudy.
(2) Insufficient feeding amount. A considerable part of the pond appears cloudy in the morning and slightly better during the day. Due to lack of feeding by farmers, the crabs find food everywhere in the evening. Excessive movement of crabs in the water will naturally cause turbidity in the water.
(3) The density is too high. Ponds with high density often have severe turbidity and low density. The turbidity of ponds with small density is generally better. The turbidity of the water in the fostering ponds is more serious than that in crab ponds because the crab density in the rearing ponds is higher than that in crab ponds.
(4) The water quality is too thin. Excessive water quality results in low levels of plankton in the water and poor buffering capacity. The cause of prolonged turbidity in the pond after mowing is due to the loss of suspended solids in the water.
solution:
(1) After water quality is turbid, firstly use "Jingshuiling" to rapidly purify water, eliminate various suspended substances in water, and reduce the content of harmful substances;
(2) Then use "Jie Po" and "Long-Effective Negative Film" to improve the bottom oxidation-reduction potential and reduce substrate organic oxygen consumption;
(3) After 5 to 10 centimeters of influent water, sprinkling chemical fertilizers combined with bio-fertilizers such as "bio-enriched treasure", and fast fertilizer and water;
(4) Finally, “Duofu Cola†was used to improve water quality, stabilize water quality, develop beneficial algae, inhibit the development of harmful algae, and form a stable water ecological environment.
