The dangerous period for new fish to enter the tank is generally about three days. During this period, they are more sensitive and need to adapt to the new water environment. If the water quality deteriorates or the water temperature is not maintained during this period, it is very likely to cause their death. In the dangerous period, it is better not to feed, feed and do not eat, residual bait left in the water will have a bad impact on the water.
1. Disinfection: Before putting new fish into the tank, make sure that the tank is safe. If there are germs, it is very easy to cause the death of the fish. Therefore, it is necessary to disinfect the tank first. Fill the jar with water, pour in potassium permanganate or chlorine dioxide, soak for a period of time, then drain the water, and then rinse with clean water. After that, you can pour water into it, and the water usually needs to be dried tap water.
2. Culture: The fish tank is a small ecosystem. In order to ensure the normal operation of this system, it is necessary to establish a nitrification system for it. Add fish food and nitrifying bacteria to the fish tank, and then blast oxygen for a period of time. Normally, the water will become cloudy and clear again in a few days. Turbid is due to the proliferation of microorganisms, which decompose organic matter to produce ammonia nitrogen, and nitrifying bacteria can convert it into nitrate.
3. Test the water: After the water is clear, it means that the water raising is completed. However, for the sake of insurance, do not put new fish into the tank. First prepare a few fish to test the water. Usually choose more solid fish, put it into the tank, raise half a month, no problem, then you can prepare new fish into the tank.
