grass turtles can be raised with pure water. Because purified water is relatively clean and not easily polluted, it is more suitable for raising grass turtles. In addition, grass turtles do not have high requirements for water quality. As long as the water is clean and fresh, they can grow normally. But most pure water is filtered and disinfected many times. Although the chemicals in it have little influence on human body, they have great influence on the daily development of grass turtles, so breeders need to pour out pure water and expose it to the sun for 2-3 days before using it. Although pure water is relatively clean, it also lacks trace elements needed by grass turtles, and the cost of feeding with pure water is relatively high, so it is best not to use it for a long time.

The grass turtles can also be raised with river water, well water and tap water, especially river water, which is more suitable for raising grass turtles. Because grass turtles live in river water when they are in the wild, raising them in river water can better restore the wild environment. But now most of the river is vulnerable to pollution, and breeders need to filter it before using it.

Tap water is easy to get, but tap water contains a lot of chlorine gas. Before use, breeders also need to expose them to the sun for several days. In addition, although the well water is not easily polluted, the temperature of the newly drilled well water is relatively low, and the breeder needs to dry it for a period of time before using it.
