salt ball usually only needs to be put in the fish tank when the fish needs to be treated. Usually, freshwater fish do not need salt at ordinary times. Increasing the osmotic pressure of the water body does not do much good to the fish. On the contrary, it will affect its health if the salinity change is not well controlled. If you raise marine fish, you need to prepare seawater, which often requires salt.
is the concentration of salt in the fish tank? 1. Three thousandths: Three thousandths is the most commonly used concentration of salt. This concentration can not play a bactericidal role, but can change the osmotic pressure of the water body, thereby reducing the possibility of bacterial invasion. For the early stage of the disease, it can play an auxiliary therapeutic role. Of course, there are some fluctuations in this concentration, but the maximum will not exceed five thousandths.
2. One percent: One percent of salt water is the commonly used concentration for sterilization. Fish cannot be kept in this concentration for a long time. Generally, they can only be soaked for a period of time, the longest time is not more than half an hour, and the shortest time is about five to ten minutes. Usually, this concentration of saline is only needed in the case of body surface lesions.
3. Three percent: The concentration of three percent is already quite high. Although the effect of sterilization and treatment is more outstanding, the fish will die quickly if the time is not well controlled. Usually, the fish can only be soaked in it for a few seconds, and then it should be immediately fished out and replaced with clean water.
