does it take to raise water in an old fish tank? It takes at least 7 days to raise water in an old fish tank. The first thing to do is to trap water, which takes about one to three days depending on the season. After that, it needs to filter and explode oxygen, which also takes a day to effectively improve the water environment. After that, it is necessary to cultivate bacteria, which often takes a long time. In the process, the water in the tank will be turbid first and then clear, so that the nitrification system can be established, so that fish can be released to raise fish.
the old fish tank 1, disinfection: the old fish tank must be disinfected. Because I don't know what I raised before and whether there will be some harmful substances left, I need to fill it with water first, then pour in a proper amount of potassium permanganate, soak it for 3-4 hours, and then drain the water and rinse it several times.
2. Raising water: After disinfection, it is necessary to raise water, because the newly received tap water can not raise fish, it must be dried, and then filtered and oxygen exploded, so as to ensure the safety of the water body. In addition, in order to create a better ecological environment, the culture solution of nitrifying bacteria can be added regularly to establish a good nitrification system.
3. Release the fish: After the water is well raised, the fish can be released. However, to be on the safe side, it is best to prepare a few fish to test the water, usually with good varieties such as grass gold. Put it into the fish tank for half a month, and then put the fish you want into it if there is no problem. If you are sick or dead, it means that the cylinder has not been opened properly and needs to be opened again.
