In breeding goldfish in winter, it is also necessary to ensure suitable water quality. After the water in the fish tank is dirty, it also needs to be replaced in time. You can use tap water at home, but you need to use it after drying. When changing water, it needs to be injected slowly, otherwise the change of water temperature will be very drastic, if the change of water temperature exceeds 2 degrees, it will lead to the phenomenon that goldfish do not adapt. Generally speaking, it is better to control the amount of water changed at one fifth or one quarter each time, and do not change too much water at one time.
1. Frequency: When changing water for goldfish in winter, the first thing to pay attention to is the frequency. In winter, the water should not be changed as frequently as in other seasons. Generally speaking, it can be changed once a week or two weeks according to the specific situation. If there are impurities in the water, you can use the filter system to clean up the impurities, do not change the water frequently.
2. Tap water treatment: The tap water used at home can be used for changing the water, but considering that it contains more chlorine, it needs to be dried before using, otherwise it will cause damage to the goldfish.
3. Time for changing water: It is necessary to pay attention to the time for changing water in winter. It is better to replace it in sunny days, so that goldfish can bask in the sun after changing water, and do not replace it in rainy days. Specifically, water can be changed from 8 to 10 in the morning and from 2 to 3 in the afternoon. However, do not choose to change water at noon, although proper sunshine is beneficial, but too strong light is not allowed.
