1. Do you want to put salt in the fish tank? Fish tanks generally don't put salt, but fish need salt when they are sick. The purpose of salt release is very simple, which is to improve the osmotic pressure of water body, so as to prevent water from penetrating into fish, which can not only prevent the invasion of germs, but also reduce the drainage burden of fish, which is helpful for their rehabilitation. However, salt alone can't cure diseases, especially in serious cases, and other drugs are needed for soaking.
2. What's the use of putting salt in fish tank1. Inhibit bacterial invasion: The main function of putting salt is to inhibit the invasion of germs. Because salt can increase the osmotic pressure of water, and water will automatically penetrate from places with low osmotic pressure to places with high osmotic pressure, the osmotic pressure of salt water is higher, so the osmotic pressure of water is higher, which can prevent bacteria from entering the body with water.
2, reduce the burden on kidneys: As mentioned above, salt can increase the osmotic pressure of water, while the osmotic pressure in freshwater fish is higher than that in water, so it is necessary to use kidneys to drain water, and less water enters, so the burden on kidneys is smaller, which is beneficial to its recovery.
3. Sterilization and disinfection: If the concentration of salt is high to a certain extent, it can play a role in sterilization and disinfection. However, in this case, salt should not be directly added to the fish tank, but the fish should be fished out and soaked in salt water, the concentration is usually 1%, and the soaking time should not be too long. If anything unusual is found, it should be fished out as soon as possible.
