In the process of fish culture, it is necessary to ensure the water quality. Changing the water is an important measure to ensure the water quality. It is necessary to pay attention to the frequency of changing the water, that is, changing the water every few days. Specifically, under different circumstances, we have different requirements for the frequency of water exchange:
1. Frequency of water exchange in different seasons: In different seasons, the specific frequency of water exchange for fish is also different. In summer, the temperature is the highest, the water quality is relatively easy to dirty, so it is recommended to shorten the interval of water change, generally speaking, 3-5 days have to be replaced once, not for a long time. In spring and autumn, it is usually changed once a week or so. There is no need to change water frequently in winter, and it can be changed once in half a month or so.
2. Whether there is a filter in the fish tank: In addition, the frequency of water change is also related to whether there is a filter in the fish tank. If the filter is prepared, or there is a strong filtration system in the fish tank, then the interval of water change can be extended appropriately.
In the process of raising fish, changing water is a relatively troublesome thing, and many farmers will think of the problem of how not to change water. If you want to keep the water, there are several aspects that need to be done. First of all, there needs to be enough nitrifying bacteria in the water, which can clean up the organic matter and nitrate in the water, so as to improve the water quality. In addition, the fish tank also needs to have a better filter system, and regularly clean the filter cartridge. In addition, some aquatic plants can be placed in the water, which can also play a role in protecting the ecological environment in the fish tank. These points are done, you can not change the water.
