the fish. If the fish is really dying, it can't be saved by salt. The reason why people think that salt can save the dying fish is that salt stimulates the fish, which causes it to twist and struggle. But this is only temporary. When it is completely dead, salt will have no effect. It should be noted that try not to put salt in the fish tank at ordinary times, only when you are sick.
of salt in the fish tank? 1. Sterilization and disinfection: Salt in the fish tank can play the role of sterilization and disinfection, and even treat fish diseases. However, it should be noted that this concentration of salt water can not soak fish for a long time, so usually do not put salt directly into the tank, but prepare a special container, which is filled with 1% concentration of salt water, and then put the fish in, soak for 3-5 minutes, too long will produce negative effects.
2. Improve the osmotic pressure: Most of the time, the purpose of adding salt to the fish tank is to improve the osmotic pressure. In this case, the salinity is usually between three and five thousandths. Although it does not have the effect of sterilization, the osmotic pressure of the water body increases, which reduces the flow of water from the outside to the fish body, thus inhibiting the invasion of bacteria. Moreover, because less water enters, it also reduces the excretion burden of the kidney.
