1, clearing pond with disinfectant, inhibiting effective bath and microbial growth;

2, long-term use of chemical fertilizers and fertilizers, resulting in excessive water quality, so that the end of the shrimp pool plate, the pool water suddenly changed, the bottom of a large number of moss growth;

3, continuous rainy days, serious lack of light.

Solution: It is recommended to change the algae source of water 20%, apply 4 kg of bio-fertilizer per mu, and use 5 kg of EM bacteria original dew to mix 5 kg of peanut bran, add 10 times of water to soak for 24 hours and then Quanchiposa, 6 hours After Mushi photosynthetic bacteria 2 kg.

About the sudden lack of oxygen after the water:

1, the use of certain oxygen-consuming biological bacteria;

2, the use of fertilizer too fast microbes;
