When raising fish, you can properly put some salt into the fish tank, which can regulate the physiological functions of fish and enhance their immunity. In addition, salt can also play a role in sterilization, which can remove some harmful bacteria in the fish tank. However, you need to pay attention to the type of salt you put in. Some iodized table salt at home is common, but this salt is not suitable for use. Although iodine is a necessary element for human beings, it is harmful to fish, which may damage their respiratory system and affect their health.
Therefore, it is recommended not to use this iodized edible salt. You can buy some special eyes for fish from the store, such as sea salt or coarse salt. These salts themselves do not contain iodine, or contain very little iodine, so they will not cause harm to the health of fish themselves. Of course, in the specific use, we must pay attention to the dosage, can not let the concentration is too high.
In the process of fish farming, regular water change is an important step. When changing water, many farmers will habitually add a certain amount of salt to the fish tank. These salts can eliminate some bacteria in the water and effectively prevent the occurrence of fish diseases, such as water mildew, gill disease and so on. However, it is not necessary to add water every time you change it. Especially for freshwater fish, their tolerance to salt is not particularly good, so it is recommended not to add it every time, but every other time. When adding, we need to pay special attention to the amount of salt and do a good job of controlling the concentration.
