In the process of raising goldfish, water quality is a more important factor. First of all, we need to choose the right water for goldfish. In the past, it was more appropriate to choose river and lake water. However, these two kinds of water are generally polluted now, and it is not convenient to take them at ordinary times, so they are not suitable. Then there is rainwater, which may contain more toxic substances, such as sulfurous acid and so on. Especially in cities with serious pollution, rainwater is not suitable for selection.
Well water is OK, it contains more minerals, but the temperature of the well water just taken is relatively low, so it is best to use it after 12 hours. Finally, tap water is the most important choice. However, considering that there is more chlorine in it, it can only be used after drying. Tap water is relatively appropriate, it has passed the stage of sterilization and disinfection, acid-base is more appropriate, hardness is more appropriate.
No matter what kind of water you choose, you must pay attention to changing the water regularly. If the water is not changed for a long time, it will lead to dirty water quality, and the growth and development of goldfish will be hindered. Generally speaking, the frequency of changing water for goldfish can be adjusted according to the season. In summer, the temperature is too high, and the water has to be changed once every three or four days. The frequency of water change in spring and autumn is the same, which can be about once a week. Winter water can not be too frequent, generally once in half a month on the line. Moreover, the amount of water exchange in winter also needs to be strictly controlled, about one fifth is better.
