will be changed. After the arrival of the new fish, the water will be changed seven days later. The reason for waiting so long is that fish need a period of time to adapt after changing the water environment. If the water is changed during the adaptation period, it will stimulate the fish and even affect their health. In addition, it should be noted that the amount of water should be strictly controlled, not all of the water should be replaced, not more than one third of the total amount of water.
1, disinfection: the first step of the new fish tank is disinfection. Newly bought fish may carry some bacteria, which, if put directly into the tank, may cause healthy fish in the tank to be infected, thus making them sick. Therefore, it is necessary to prepare some potassium permanganate mixed with water and soak the fish in it for a period of time.
2. Overheating: As there may be a temperature difference between the water filled with new fish and the water in the tank, changing the fish to another environment rashly may be affected, so it is necessary to overheat in advance. Slowly put the bag of fish into the upper layer of the fish tank, but do not put the mouth of the bag into it, and wait for the temperature of the two to gradually become the same.
3. Water passing: After the temperature is passed, the water can be passed. Water passing is the last step of closing the jar. The water in the bag and the water in the tank are exchanged step by step. Each exchange should be separated by a period of time. Usually after five times, the water is completed. The bag can be lowered to let the fish swim out and the bag can be taken away.
