changing the water in the fish tank, if you find the fish lying in the tank, you need to rest for a period of time, during which you should keep the water temperature, do not feed and change the water, and wait for it to adapt slowly. The reason is that the fish can not adapt to the new water because of the large amount of water, but this situation is not very serious, as long as the fish slowly adapt, if it is caused by disease and other factors, it needs sterilization treatment.
correctly 1. Trapped water ahead of time: If you want to change water correctly, the first step is to trap water. After the water is connected, do not immediately change the fish tank, but put it in a sunny place to dry for a few days, usually the least time in summer, only about a day, two days in spring and autumn, the longest in winter, three days.
2. Adjust the water temperature: Make sure that the water temperature is consistent before and after changing the water, otherwise the temperature fluctuation will also cause harm to the fish. Therefore, we need to measure the temperature of the old water first, and then mix the new water according to this temperature. We can add cold water or hot water to it, so that the temperature of the new water is close to that of the old water.
3. Pump water and inject water: Usually, the water inside needs to be pumped out first. Generally, a water pump can be used. You can also find a pipe and use the siphon method to pump the water away. Water should be injected after pumping, and it is better to add water slowly from the wall of the tank, so as to avoid the fluctuation of the water body after violent water change.
