After half a year of feed feeding and high temperature in summer, the pond's relative density increases. The residual water in the water, the fish's excrement, and the decay of old leaves will consume a lot of oxygen. The ammonia and nitrite in the water are too high, and the pH value drops. , It is very easy to cause flooding of fish floating ponds, leading to the occurrence of hemorrhagic disease, so pay special attention to the following aspects of regulation.
First, Qinjiang New Water
For a pond with a convenient water source, the pond should be filled with fresh water every 10 days or so. Normally, the pond should be filled with water at a maximum level of 20 centimeters each time. It is better to add fresh water in the early morning. Do not pour water into the pond at 3-5 p.m. to avoid causing the fish to float.
The second is diligent oxygen increase
The correct use of aerators, adhere to open at noon on a sunny day, do not open in the evening, open early in the morning on cloudy days, not open during the day, open before the floating head, the principle of continuous open rainy nights.
Third, diligently adjust water quality
The limestone slurry should be splashed on a regular basis in order to neutralize acids and reduce the acidity of the water so that the water can maintain a suitable pH environment. About half a month in sunny days, Bacillus, photosynthetic bacteria, and EM bacteria are used to adjust water quality, reduce the harm of nitrite, ammonia nitrogen, hydrogen sulfide and other toxic and harmful substances to fish, and reduce the occurrence of diseases.
