Put a proper amount of salt in the fish tank, which can play a variety of roles such as sterilization and stimulating the appetite of fish, but you need to pay attention to the frequency of putting salt. First of all, when you just bought a fish tank, it is best to carry out a certain sterilization and disinfection treatment, first of all, you can use high concentration salt water to clean the fish tank as a whole, and then use a slightly lower concentration of salt water to soak the fish tank, about a day or so, so that after treatment, you can start fish farming.
After that, it is the process of raising fish. Although the benefits of salt are more, considering that salt may have a certain impact on water quality, and putting too much is also harmful to fish themselves, especially for salt-tolerant freshwater fish. Therefore, usually can not add salt, or add a small amount of salt, the concentration must not exceed 0.5%. When fish are sick, they can be treated by adding salt, and the frequency of adding salt can be controlled once a week until the disease is cured.
After adding salt in the fish tank, you need to pay attention to the problem of changing the water. Salt in water can inhibit bacterial reproduction and disinfect. After adding salt, you can generally wait until 2 or 3 days before changing the water. After putting salt, it does not mean that there is no need to change water, and it can not be changed for a long time. Also need to pay attention to the problem of water exchange, generally speaking, a quarter of the total water can be replaced, not all replaced.
