Turtles like clean water. Clean water is beneficial to the health of turtles. Tap water, purified water, cool boiled water, sterilized water, or filtered water are all acceptable.

In fact, the most suitable water quality for turtles is ecologically balanced water, such as green water with a balanced algae and bacterial flora, and old water that has been exposed to sunlight. This type of water quality can increase the turtle's sense of security, reduce rotten skin and armor, and is beneficial to hair color. However, green water requires a large water body and a certain amount of energy, so it is generally not recommended to try it.

When raising a turtle, you should pay attention to changing the water. Changing the water for it is different from changing the water for the fish. You should not change the water for the fish too much or too often, because the fish are dependent on water. It is very sensitive, and once the water environment changes, it will be greatly stimulated.

When changing the water for a turtle, you must change it completely, because its excrement will pollute the water quality and cause the water to stink. There is no need to retain this kind of water.
