It usually takes 6 to 9 days to keep the water in a new fish tank. For some fish with strong adaptability, it may only take 2 to 4 days to keep them. However, keeping the water for a longer time will be safer for the fish.
1. Water drying: People who raise fish all know that the tap water they just received cannot be used directly, because the tap water will have chlorine residue in the process of disinfection, which is fatal to the fish, so it must be dried for a few days before it can be used. Tap water is usually placed in the sun and exposed to the sun to remove chlorine quickly, which usually takes several days. If you want to remove chlorine quickly, you can also use oxygenation equipment to oxygenate the water, as long as 2-3 hours.
2. Culture: Although there are no harmful substances in the aired water, it also lacks some beneficial ingredients for the fish. At this time, it is necessary to add a proper amount of nitrifying bacteria to the water, which is a kind of bacteria that can decompose harmful substances and convert ammonia in the tank into nitrate, which can be absorbed by plants in the water. Without it, the ammonia content in the water is too high, which will lead to the death of fish. Therefore, it is an important part of maintaining ecological balance.
3. Test the water: With the nitrifying bacteria, the water is suitable for fish farming, but it is still not very safe to release the fish at this time. In order to ensure that the water body is suitable for fish farming, it is necessary to first release a few fish into the tank to test the water. Generally, it is necessary to select fish with solid skin and good breeding. If the fish that is not easy to raise dies, you cannot judge whether it is a problem with the water. As long as you can live for a period of time, you can put the fish you want to raise into it.
