There are many reasons for the turbid and yellow water in the newly opened fish pond, such as the large amount of suspended organic matter, the imbalance of nutrition in the water body, the deterioration of the bottom material, and the illness of the fish. If you want to make the water clear, you must regularly add new water, at the same time, properly oxygenate, and add some microbial agents to remove residual bait, dirt and so on, which can improve the water quality.
1. Continuous rain: In case of continuous rainy weather, the rain will wash the mud around the pond into the water, which will cause the water to become turbid. Usually after sunny days, the water will slowly recover, if you want to improve quickly, you can add a little alum or polyaluminium chloride flocculant to the water.
2. No colloidal layer: Generally, the bottom of a newly opened fish pond has not yet formed a colloidal layer. Therefore, some fish that like to stay at the bottom of the water will move around and arch up the silt at the bottom of the water, which will cause the water to be turbid. In view of this situation, timely fertilization is needed to let algae grow out, which can be effectively controlled.
3. Rotifer reproduction: Generally, in the stage of cultivating water spray, it is necessary to provide certain rotifers as food. However, after the fish grow up, if there are still a large number of rotifers in the pond, it will also make the water turbid, and it will also cause the fish to lack oxygen. At this time, it is necessary to kill them with drugs.
