Ornamental fish generally use tap water to raise. It should be noted that when the waterworks disinfect the tap water, there will be chlorine residues, although the content is very low, but there is a great threat to the health of fish, so it is necessary to remove chlorine first. The treatment method is relatively simple, as long as the water is dried for a few days. It is generally not recommended to use river water or well water to raise fish, because it is uncertain whether these water bodies are polluted.
1. Disinfection: The first step in opening the jar to raise water is to disinfect the water jar. No matter it is a new jar or an old jar, it should be disinfected to avoid unexpected situations. The method of disinfection is very simple, as long as the jar is filled with water, then add potassium permanganate, soak for 3-4 hours, then drain water, and then rinse it with clean water. If you feel too troublesome, you can also spray potassium permanganate solution on the surface of the fish tank, and then wipe and wash it.
2. Culture: After disinfection, water can be injected into the water tank. General water injection more trapped water, just tap water can also be, because in a short period of time will not be fish. When the water is full, add a little fish food to it, and then pour in the nitrifying bacteria. It is very important to establish a nitrification system for fish farming. The purpose of releasing fish food is to let heterotrophic bacteria decompose organic matter and produce ammonia nitrogen, while digestive bacteria convert ammonia nitrogen into nitrate. In the process, the water in the fish tank will be turbid first, and then become clear, which indicates that the nitrification system has been established.
3. Test the water: In order to ensure that the water body has adapted to the survival of the fish, you need to test the water with the fish in the tank first. Generally choose some of the more solid fish, put it into the tank to see if there will be pathological changes or death, if there is no problem for half a month, you can put the fish in. If the fish in the tank dies, the tank needs to be reopened.
