Just bought the fish tank is not directly fish, must first clean, but also to disinfect it. Disinfection usually uses potassium permanganate or sea salt, which is poured into the solution, the concentration is not too high, and then it is cleaned again. If you want to put some decorations in the tank, you should also clean and disinfect them, so as not to threaten the health of the fish.
After the fish tank is cleaned, it can not be used to raise fish immediately, it needs to add water to stand for a few days. If conditions permit, you can directly release the trapped water, otherwise you can only add tap water. Because tap water contains chlorine, putting in fish will lead to its death, so it is necessary to open the filter and let it stand for a few days, so that it can play a role in removing chlorine. In addition, if you want to raise tropical fish, it is best to preheat with a heating rod.
If the feces discharged by the fish are not cleaned up in the fish tank for a long time, the overall water quality will be affected, but if there are nitrifying bacteria, this can be effectively improved. After the water in the fish tank has been filtered for a period of time, the nitrifying bacteria can be added. Usually after adding the water will become cloudy, this time can put a little fish food or shrimp to let them decompose, usually three to five days later will be decomposed, the water will become clear, but also sticky.
The above three steps are the method of opening the tank, but it is still unknown whether the water is suitable for fish farming. At this time, don't rashly put the fish in. First prepare a few fish to break into the tank, and choose some relatively solid varieties to see if they can adapt to this environment. If they can grow normally, You can put other fish in it.
