Tortoises are well raised with cold boiled water. Liangbaikai is usually cooled after boiling tap water. Tap water is not polluted after disinfection. It can also be used to raise turtles, but it needs to be trapped to remove chlorine. Boiling can accelerate the volatilization of chlorine, and at the same time, it can separate out impurities in water, reducing the overall hardness, which is also good for the health of turtles. In addition, it can ensure that there are no bacteria in the water, thus preventing diseases.

1. Water quality: Turtles soak in water most of the day, so they have higher requirements for water quality. If the water quality is not good, it is easy to cause them to get sick. In order to improve the water condition, the water should be changed every three days, and all of them should be changed. When changing the water, the dirty things in the feeding tank should be cleaned up by the way.

2. Water temperature: As mentioned above, turtles have certain requirements on water temperature, not only to keep high temperature, but also to control constant temperature. Once the temperature changes, turtles are prone to colds, pneumonia and other diseases, which are very troublesome to treat, and even lead to turtles dying.

3. Water level: To raise a turtle, it needs to be soaked in water. Generally, the water level is not above the turtle's back. If it is a deep-water turtle, the water level can be higher, but it is not raised in deep water at the beginning. The water level must be raised slowly so that the turtle can adapt.
