The new fish tank should be disinfected first, so as not to cause the fish to get sick. Fill the fish tank with water, then pour in potassium permanganate, soak for 3-4 hours and then drain the water, and then rinse with clean water to avoid drug residues. If you think this method is troublesome, you can also put potassium permanganate solution into the watering can, then spray it to the water tank, and then wipe it clean with a rag.
1. Trapped water: The first step of opening the jar is to add water to the jar, but the added water cannot be casually received. Generally, tap water should be used. After disinfection, the tap water is safer than river water or well water. However, because it contains chlorine, you need to trap the water before using it, and put it in the sun for a few days. It can only be used after being exposed to the sun.
2. Culturing bacteria: The second step of opening the jar is culturing bacteria. The bacteria here refer to nitrifying bacteria, which can absorb ammonia nitrogen produced by other bacteria when decomposing organic matter, thus reducing the risk of poisoning fish. The method of cultivating bacteria is also very simple, after pouring nitrifying bacteria into water, put a little fish food, and then give it oxygen explosion. When the fish food disappeared, the water became turbid and clear, indicating that the nitrification system was completed.
3. Release the fish: The last step of opening the tank is to release the fish. To be on the safe side, you can first put a few fish into the tank to have a try. If the fish can be raised alive, then put the fish to be raised into the tank. You should feed the bait regularly, and pay attention to changing the water at the same time.
