If the fish tank has dead fish, it is necessary to fish out the dead fish in time to avoid polluting the water quality after they rot. If there is a continuous death of fish, it may be a problem with the tank. At this time, the live fish needs to be fished out first, temporarily packed in bags or other containers, then the fish tank should be disinfected, filled with water and poured into salt or coarse salt, soaked for 1-2 days, then drained and wiped dry, and then poured into the raised water, and then put the fish back.
1, disinfection: re-open the tank must be disinfected first, so as to ensure that the tank will not have problems. Disinfection drugs generally choose potassium permanganate or chlorine dioxide, soak the fish tank for a period of time, drain the water and wash it several times, so as to complete the disinfection.
2. Raising water: To raise fish, you must first raise good water. Bad water is also the key to the death of fish. The first step is to raise water trapped water, will be connected to the good tap water to the sunny place drying, drying 1-2 days on the trapped water. The trapped water is injected into the fish tank, filtered and oxygenated to make the water clear, and nitrifying bacteria are poured in to establish a nitrification system, so that the water can be well maintained.
3. Test the water: After raising the water, do not immediately release the fish. First find a few fish that run into the tank to test the water. Generally, choose fish that are more solid and easy to raise. If it is no problem to raise them for half a month, then put the fish you want to raise into the water. If the fish in the tank is sick or dead, they need to continue to try after changing the water, or turn the tank directly.
