Yellow powder as a kind of fish medicine that people often use has a good bactericidal effect, it is very convenient to use, and can treat many fish diseases, such as rotten tail disease, rotten fin disease, etc., and also has a certain therapeutic effect on enteritis. Yellow powder is commonly known, its scientific names are furacillin and furazolidone. Let's talk about the use of yellow powder and precautions.
First: the difference between imported yellow powder and domestic yellow powder
The main ingredient of domestic yellow powder is furacillin, which belongs to the nitrofuran class of drugs, and is the lowest price and the lowest difficulty in production. Although its price is low and the medicinal effect is good, the toxicity of this drug is a big problem, and it belongs to the most toxic nitrofuran drugs. The toxicity level has reached a high toxicity level, so I see a lot of aquarists spreading throughout the pool, and the back spine is cold. Relatively speaking, Japanese yellow powder has a good effect, little toxicity, and according to his instructions for use, it is very good. Because its main component is sodium furan-phenylenoate, it also belongs to the nitrofuran class of drugs, and its toxicity is relatively small.
Second: Pay attention to temperature and light conditions
Yellow powder has requirements for temperature, if the water temperature is low, then yellow powder is not effective. If you want the best effect of yellow powder, then it is best to control the water temperature above 20 degrees. In no light or low brightness conditions, the concentration of yellow powder after dissolving in water can remain unchanged for one week; under high brightness or light conditions, the concentration of the agent will decrease rapidly. Recommended for indoor or out-of-the-dark use.
Third: pay attention to pH
When yellow powder is used, the PH of water is the most acidic. Of course, in neutral and slightly alkaline water, yellow powder can also play an effect, but slightly worse. If the PH is more than 9, the effect of yellow powder is very poor, so if you want yellow powder to play the best effect, you also need to control the pH of the water.
Fourth: pay attention to oxygenation
If it is not a separate medicinal bath, it is necessary to put yellow powder in the whole tank, then it is best to open the oxygenation equipment. Because yellow powder is powder after all, putting it into the aquarium will lead to lack of oxygen in the water body and affect the normal life of the fish. Opening the oxygenation equipment to oxygenate the aquarium can effectively solve this problem and help the recovery of sick fish.
