in the fish tank in winter? It is not necessary to change the water in the fish tank too frequently in winter. If you change it every few days in spring and summer, you can change it once a week in winter. The water quality is maintained well at ordinary times, or even once a half month. Before changing the water, you need to put it in a sunny place to dry for a few days. The purpose of doing so is to dissipate the original residual chlorine in the water, so as to ensure the health of the fish. In addition, violent water changes should be avoided to avoid fluctuations in water quality.
for water change? 1. Pay attention to the frequency: First of all, pay attention to the frequency of water change. According to the size of the fish tank and the density of fish farming, the cycle of water change is also quite different. If the water quality is deteriorating, you can change the water. If you change it frequently, you can change it every three or five days. If you don't change it frequently, you can change it every half month.
2. Pay attention to the amount of water: according to the different cycles of water change, the amount of each change is also different. If you change more frequently, don't change more each time. Usually, you can change one fifth. If you are lazy, you can increase the amount of water to about one third, so as to better maintain the water quality.
3. Pay attention to the temperature: Another issue that needs to be paid attention to is the water temperature. Temperature changes are also very stimulating to fish, and the temperature can be consistent before and after changing water, if there is a difference, usually not more than 1-2 degrees Celsius, so as to ensure the health of fish.
