It is better for turtles to change water every two days. Changing water for turtles is generally more frequent, because they eat more and are excreted in water. If they don't change water for a long time, the water quality will deteriorate, which will lead to white eye disease, skin rot and other diseases. Every time you change water, you must ensure the same temperature, otherwise it may cause irritation. In addition, change the water completely, and pay attention to clean up the unfinished food and its feces when changing.

1. Dry in advance: Tap water is used to change water for turtles. This water contains residual chlorine, which is harmful to the health of turtles, so it is necessary to dry and remove chlorine. Put the connected water in a sunny place and bask in it for 1-2 days. If it is cloudy, you can let it stand for a week and let chlorine volatilize clean.

2. How much water to change: Because turtles are usually raised in shallow water, the amount of water is not very large, and their excretion is relatively large, the water quality is difficult to maintain. Every time you change water, you need to change it all. If the water depth is a little deeper, you can change it by half. In addition, when changing water, the excrement inside should be cleaned up.

3. Precautions: Turtles are sensitive to temperature changes. If the temperature difference is too large, it will easily lead to colds or pneumonia. Therefore, it is necessary to keep a constant temperature before and after changing water, usually above 20 ℃.
