when the water in the fish pond is black? If the water in the fish pond is black, it takes a lot of effort to restore the clarity. First of all, we should do a good job of cleaning the pond, dig out the excess silt at the bottom of the pond, and solve the problem of water blackening from the source. Then to disinfect properly, usually sprinkle the whole pond with quicklime, or change the bottom with other medicines. In addition, biological control methods are also very good, regularly supplement some beneficial bacteria to improve the ecological conditions at the bottom of the pond.
of blackening? 1. Water eutrophication: The main cause of water blackening is eutrophication. The reason for eutrophication is that the feeding amount is too large at ordinary times, so it is necessary to control the use of bait and improve the utilization rate of feed. In addition, we should also pay attention to salvage in peacetime, clean up the moss of aquatic plants, and prevent the deterioration of the water body.
2. Apply too much fertilizer: In order to fertilize the water body, fertilize the pond at ordinary times, but fertilization is not unlimited, if too much fertilizer is applied, it will also have a negative effect. The purpose of fertilization is to cultivate plankton, which can be used as bait for some fish and facilitate the feeding of some filter-feeding fish.
3. The water in the fish pond is too deep: If the water in the fish pond is too deep and the oxygenation capacity is very poor, the oxygen at the bottom of the pond is relatively deficient, which will lead to corruption and stink. Therefore, the installation position of the aerator should be selected to form a certain angle with the pool wall, so as to improve the dissolved oxygen at the bottom of the water.
