How to change water for goldfish and the correct method of changing water for goldfish

Changing water is an important step in the maintenance process of goldfish. The frequency of water change can be adjusted according to the season. In addition, if there is a filter, the frequency of water change can be reduced. You can use river water and lake water to change water. If you use tap water, you must dry it before reuse. The water change volume is generally one-third or one-quarter. When changing the water, it is also necessary to clean up the impurities in the water in time. After changing water, if goldfish don't adapt, you can supplement some oxygen slightly. 1、 The frequency of water change is very important in the process of maintenance. The first problem is the frequency problem. Generally speaking, it can be adjusted according to the season. The problem is the highest in summer. Generally speaking, you have to change the water every three or four days. In spring and autumn, it can be about once a week. If it is winter, it is generally about once every 10 days. However, the frequency of water change is not certain, it is also closely related to other factors. For example, if there is a filter in the fish tank, the water change will not be too frequent. 2、 Changing water quality what water to use when changing water is also a very important issue. Generally speaking, river water and lake water are more appropriate, but we need to choose river water and lake water that have not been polluted. If the water is not easy to use, tap water can be used at home. However, tap water can not be used directly. It needs to be dried for a period of time before it can be used. 3、 During the water change process, you can't change too much water at one time. Just control it to one quarter to one third of the whole. Moreover, when changing the water, the flow rate of the water should not be too fast, otherwise it is easy to cause a sharp change in the temperature of the water, and the goldfish may have an inappropriate situation. In addition, when changing water, you can clean up other sundries in the fish tank, so as to avoid new water pollution. Specifically, impurities can be sucked out with a special pipe. After changing the water, goldfish may not adapt, which may be caused by the lack of oxygen in the water. You can supplement some oxygen slightly. （JinYuRuHeHuanShui，JinYuHuanShuiDeZhengQueFangFaJieShao）
