breeding goldfish, water quality is very important on the one hand. In order to ensure that the water quality is always clean, it is necessary to change the water regularly. However, the frequency of water change is related to many factors, and it is impossible to determine a certain frequency.
1. The specific time for changing water is closely related to whether there is filtering equipment in the water. If there is no filtering equipment in the water, then the water in the fish tank will be dirty in about 2-3 days, so it needs to be changed in time. If there is filtering equipment in the water, then the water body will be relatively clean for a relatively long period of time, you can change the water once in about 10 days or even half a month, there will be no problem.
2. The frequency of water exchange is also related to the season. If the temperature is relatively high in spring and summer, then the water needs to be changed relatively frequently. If it is in winter, the interval of water exchange can be relatively long.
3. In addition, whether to change the water can also be determined by observing the state of the water body. If there are many impurities in the water, it is necessary to change the water in time, if the water body is relatively clean, you can temporarily do not need to change the water.
to goldfish for water, you can use lake water, river water or well water and so on. However, when using lake and river water, we need to pay attention to pollution problems, polluted water can not be used. If well water is used, special attention should be paid to the temperature problem, and it is better to use it after drying. Besides these water, the most convenient thing is tap water. However, tap water can not be used immediately, because it contains substances harmful to goldfish. If you want to use it, you need to dry it for a period of time before you can use it.
