In the process of breeding koi, regular water change is a very important step. Then, we need to pay attention to how often we need to change water. However, this is not very sure, the frequency of water change is related to many factors. For example, the season has a greater impact on the frequency of water exchange. In summer, when the temperature is relatively high, it is required to change water frequently, in two or three days to change water once; However, in winter when the temperature is relatively low, then the interval between water changes can be longer, according to the situation in a week to two weeks can change water once.
Moreover, whether there is a filtering device in the fish tank has a great impact on the frequency of water change. If there is filtering equipment, the water in the fish tank is not easy to get dirty, and the interval between water changes can naturally be longer; Without filtration equipment, many impurities are easy to appear in the water, so the water needs to be changed frequently. Therefore, the specific time to change, can be judged by observing the state of the water in the fish tank.
Koi is a kind of freshwater fish, so it is better to raise it with river or lake water, which contains more minerals and so on. However, sometimes the river and lake water are not easy to get, so we can only use tap water to breed. Tap water is also OK, but if it contains too much chlorine, it will cause harm to fish gills. Therefore, the tap water used in peacetime needs to be left standing and aired before it can be used for Koi.
