3. Fish farming medicine that does not require water changes?

The fish tank with potassium permanganate does not need to change the water. Give the fish time to adapt to avoid discomfort and collision with the tank.

You do not need to change the water after adding potassium permanganate to the fish tank, because potassium permanganate itself has a disinfecting effect and does no harm to fish. On the contrary, it can disinfect the fish tank and fishing gear.

First, there is no need to change the water in the fish tank with potassium permanganate. The potassium permanganate in the fish tank is used to disinfect the fish tank and fishing gear. In particular, the newly purchased fish tank must be disinfected with potassium permanganate, otherwise it will make the fish sick, such as tail rot, fin rot and other diseases.

Second, it is recommended to change the water in the fish tank several times. The general water should be changed first, and then all the water should be changed to give the fish time to adapt to avoid discomfort to the fish and collision of the cylinder. The frequency of water change is usually one to two times a week. If the water quality changes too much, fish that are slightly sensitive to water quality may feel uncomfortable. When changing the water, we should also remove the dirt at the bottom.

1) Halogens: such as bleaching powder, chlorine-bromine preparations, dichloro preparations, iodine preparations, etc. These drugs can effectively inhibit and kill bacteria, especially organic iodine is now recognized as an effective drug for inhibiting and killing viruses. 2) Heavy metal copper: such as organic copper and copper sulfate. Copper sulfate is quite effective in killing protozoa, but one thing is that it is relatively toxic. Organic copper can make up for this without affecting the effect. 3) Pesticides: Common ones include trichlorfon, etc. This type of drug has a significant effect and is commonly used in economic fish farming and ornamental fish farms, but is rarely used in family ornamental fish. 4) Furans: Furazolidone, mostly used for body surface disinfection. Furazolidone, mostly used for enteritis, but has side effects. 5) Antibiotics: This is the most effective class of drugs for inhibiting and killing bacteria, viruses and molds. However, it should be used with caution. Long-term use will produce drug resistance and make the drug ineffective. Common ones include penicillin: It has a good effect on bacteria, viruses and molds. Gentamycin: The effect is similar to penicillin and is often used alternately with it. Oxytetracycline: It has excellent inhibitory and killing effects on bacteria and viruses, and it works quickly, but its biggest disadvantage is that mold is immune to it. Erythromycin: It is not used much, and it is commonly used externally, such as for rotten meat and rotten fins. Its characteristic is that it develops resistance quickly. Generally, the drug will basically become ineffective after 3 days of use, and it can only be used again after about two months. Therefore, when using antibiotics, you must pay attention to replacement and mixing to avoid pathogens from developing resistance. It is best to use it when you have no choice. 6) Chinese herbal medicine: This is some emerging fish medicine, which has the characteristics of high efficacy, fast effect, and non-toxicity. Commonly used garlic: Allicin inhibits Gram-positive and Gram-negative bacteria. It has inhibitory and killing effects on most pathogenic fungi and Candida albicans. Its water extract can kill protozoa and is mainly used to treat bacterial enteritis and vertical scale disease. It can be mixed with erbium feed for oral administration during treatment, or it can be used to soak sick animals. There are also rhubarb, coptis chinensis, etc. 7) Other categories: Potassium permanganate: A strong oxidant, commonly used for medicated baths and quarantine of new fish, it is extremely unstable and must be prepared and used immediately.
