Pet turtles usually change water once every two days. Raising turtles is different from raising fish. The water used for raising turtles is generally less, and it is usually enough without the turtle's back. Moreover, when it eats in the water at ordinary times, it will produce a lot of food debris, which is difficult to clean up when entering the water and pollutes the water body. Therefore, it is necessary to change water frequently, so as to ensure the health of turtles. If the water is not changed for a long time, the deterioration of water quality will easily lead to skin rot.

1. Trapping water in advance: Tap water is generally used to change water for turtles. Like fish farming, such water needs to be dried first, which can effectively remove chlorine and prevent residual chlorine from harming turtles. There are many ways to trap water. Besides drying, you can also use oxygen pump to aeration for a period of time.

2. How much water to change: Unlike fish farming, turtle farming usually needs to change all the water, because the water used for turtle farming is very small, which usually only passes through the turtle's back, and its excretion is very large, so it is easy to pollute the water body. In this case, it is necessary to change all the water, otherwise it will not improve the water quality.

3. Pay attention to water temperature: Pay attention to water temperature before changing water to ensure that the temperature will not change after changing water. Usually, water is placed indoors, so it is consistent with room temperature, and no additional temperature change is needed.
