If the bottom of the shrimp pond is too dark or too much before the seedlings are released, the bottom can be dried for a long time during the pond drying period, and even some silt can be removed. In addition, the amount of lime is increased during disinfection, and at the same time, quicklime is fully combined with sediments, which can accelerate the decomposition of organic matter.
If the color of mud in the pond is too dark during the culture process, which affects shrimp, this situation should be mainly based on water transfer. In addition, we should also consider whether the daily feeding amount is reasonable. As long as the feeding is reasonable, using drugs to adjust water can completely change this situation. In this case, the most commonly used medicine is potassium bisulfate, which is a quick-acting medicine. The specific dosage varies according to the drug content, so be sure to see the drug content clearly before use.
After using potassium bisulfate, probiotics, such as Bacillus and Lactobacillus, can be reused in water after three days. The purpose of this time is to cultivate probiotics in the water, so that probiotics can decompose too much organic matter in the water and prevent the bottom of the pool from blackening due to too much organic matter.
In addition, it should be noted that in this process, we should pay attention to the dissolved oxygen in the water and make sure that the dissolved oxygen in the water is sufficient. Otherwise, the effect will not be ideal after taking the medicine. The best way is to turn on the aerator in the pond after taking the medicine.
Causes of blackening at the bottom of the pool
The rapid blackening of the bottom of the pond is one of the reasons for the aging of the shrimp pond, and the blackening of the bottom of the pond is caused by the deposition of organic matter in the shrimp pond. Not only that, organic matter decays and decomposes under the action of bacteria, and also produces hydrogen sulfide. Therefore, in places where the pond is seriously blackened, crayfish are likely to be poisoned (loss of appetite, weakened breathing, weak crustaceans, black cheeks) and so on. Generally speaking, the bottom of the pond turns black for the following reasons: 1. The water quality in the pond is too fat, and the organic matter is decomposed by bacteria. 2. Many dead grasses sink to the bottom of the pond. 3. If the bait is put into the bottom of the pond too much, it will go bad.
How to change the black matrix quickly
If the black matrix is found in time, immediate action is needed. First, change the water in the shrimp pond (not once, but in several cycles). In sunny days, bacteria poison can be used for quick-acting treatment, and oxygen tablets or oxygen-increasing granules can be used at night. In addition, combined with the use of bottom modified purification particles, ammonia+water purification EM bacteria, and if necessary, high-quality water rich in algae phase can be introduced to cultivate beneficial algae.
