in winter? If you want to keep the water temperature in winter, you must first ensure that the temperature in the cylinder will not change, so you need to prepare a heating rod to control the temperature, so as to control the temperature of the new water. After the water temperature in the jar is determined, the new water can be added with hot water to raise the water temperature. Do not add too much water each time. Otherwise, add cold water when the temperature is high. Stir it after adding water. When the water temperature is 1-2 ℃, it can be used.
in winter 1. Water change cycle: It is not necessary to change water too frequently in winter. On the one hand, it is to prevent stimulating fish. On the other hand, because of the low temperature environment, the water quality can be better maintained without worrying about the deterioration of the water body. If you change it every few days before, you can change it once a week or two in winter.
2. Method of changing water: No matter which season the water is changed, the method will not change much. First prepare the new water to be replaced, then pump out the old water in the jar. Generally, it is enough to pump out a quarter of the total amount of water, and then pour the new water into it. When pouring, it should fall from the wall of the jar.
3. Precautions: To change the water in the fish tank, first of all, avoid changing the water violently, because this will cause fluctuations in water quality and temperature, which is harmful to the health of the fish. In addition, the new water must be dried in advance, so as to remove the residual chlorine in the water.
