1. Is it OK to add salt to fish when they are sick It is OK to add salt to fish when they are sick. The purpose of adding salt is not to disinfect and sterilize, because the concentration of sterilized saline is very high, which is harmful to the health of fish. Usually, salt is added only to increase the osmotic pressure of water body. Because the temperature needs to be raised during the treatment, the temperature will accelerate the reproduction of bacteria. In order to prevent the invasion of bacteria, salt is added to increase the osmotic pressure and reduce the possibility of water infiltration, thus avoiding the aggravation of the disease.
2. How to treat fish when they are sick1. Change water: You must change water when raising fish, but the change of water in the old three samples is different from that in peacetime. Usually, the change of water is usually once a week, and even once every half month if the water quality is kept good. However, the water in the old three samples should be changed every other day, so as to improve the water quality as soon as possible and reduce the content of harmful substances in the water to prevent the illness from getting worse.
2. Temperature rise: Many diseases are caused by low temperature, because low temperature will lead to the decline of its resistance. By proper temperature rise, it can stimulate its immune system and increase its metabolism, thus expelling harmful substances faster, which is very helpful for subsequent rehabilitation.
3. Salting: Salt water can play a role in disinfection, but salt is not given to fish tanks for disinfection, because sterilized salt water has certain requirements for concentration. At this time, salt should not be lowered too much, and the concentration should be controlled at about three to five thousandths, which can improve the osmotic pressure of water and reduce the possibility of harmful bacteria invading fish.
