The function of oxytetracycline is to diminish inflammation. It is usually OK to soak it for 4-6 hours. If it is sprinkled in the whole jar, the concentration must be controlled. Usually, the time of medicated bath will lose its effect after 24-48 hours, after medication, it usually takes two days to change water, the amount of water is about a quarter, and after changing water, it will continue to put medicine according to the amount of water.
1, change the water: fish sick, the first thing to do is to change the water, and the difference between the normal water change is that this time to change water frequently, usually every day or every other day for a change. The purpose of changing water is to reduce the content of bacteria in the water body and gradually improve the water quality, which is very helpful for the recovery of fish.
2. Heating up: After changing the water, the next step is to heat up the water properly. Compared with peacetime, the water temperature at this time is 1-2 C higher, raising the water temperature can stimulate the fish body, accelerate its metabolism, but also improve its resistance. However, warming can also lead to accelerated reproduction of pathogens, so appropriate salt is needed.
3. Adding salt: The purpose of adding salt is to change the osmotic pressure of the water body. Because the osmotic pressure of the freshwater fish is higher than that of the water body, water will continuously permeate from the body surface, and germs will also invade. By adding salt to increase the osmoic pressure, the speed of water entering can be reduced, thus helping it to recover.
