the fish tank water suddenly becomes turbid is usually only one reason, that is, the nitrification system collapses. Fish farming should not only pay attention to the situation of fish, but also pay attention to the quality of water. Many beneficial bacteria in water are essential, such as nitrifying bacteria, which can convert ammonia nitrogen produced by the decomposition of organic matter. If nitrifying bacteria die out in large numbers, microorganisms will multiply in large numbers, resulting in biological turbidity.
for fish farming 1. Change water regularly: The most direct way to improve the water environment is to change water regularly. There is no fixed cycle for water change, and preparations need to be made in advance according to the change of water quality. Because tap water is usually used, it is necessary to remove chlorine for a few days first. Then, before the water quality deteriorates, it is necessary to replace a part, usually about a quarter at a time.
2. Strengthen filtration: If there is filtration in the fish tank, the water quality can be well maintained, but the effect of filtration will be weakened after a long time. At this time, it is necessary to strengthen filtration. If the water pump can be adjusted, you can try to increase its power, and pay attention to cleaning the filter cotton, usually every three months, and wash it with the original tank water.
3. Reduce feeding: The ammonia nitrogen content in the water is too high, which is also related to the usual feeding. Usually, you can't feed too much. You can feed two to three times a day. After each feeding, you should ensure that the fish can finish eating within 3-5 minutes, so that the water quality will not deteriorate.
