After the fish grows white hair, the first thing to do is to change the water for it, because the white hair is caused by fungi, by changing the water can reduce the number of fungi in the water body, which is very helpful for its recovery. It should be noted that the water should be changed every other day, about a quarter of each time, so as to improve the water quality.
In addition to changing the water, we should also pay attention to temperature rise, because this disease is caused by too low temperature, temperature rise can prevent further deterioration of the disease, but also can stimulate the resistance of the fish, accelerate metabolism, for the recovery of the fish is very helpful. However, heating up will accelerate the reproduction of harmful bacteria, so salt is also needed.
Generally, it is not necessary to add too much salt, and it is OK to keep it at about three to five thousandths. After changing the water each time, the salt should be added according to the amount of water changed. The purpose of salt is to change the osmotic pressure, which can reduce the burden of kidney drainage, but also to avoid harmful bacteria entering the fish with the water, to prevent the aggravation of the disease.
If the condition is more serious, the old three alone is not cured, but also need to take a medicated bath. It can be soaked in povidone iodine solution, 20 mg per liter of water, or soaked in potassium permanganate mixed brine for about 20-30 minutes.
