Green water for raising turtles needs to be obtained from the wild. Green water turns green because there are a large number of Chlorella in the water, which can maintain the water quality well and prevent the occurrence of skin rot, so it is very good for raising turtles. It should be noted that it is not enough to introduce green water, but to provide proper illumination, and it is best to filter so that the water quality will not deteriorate.

1. Preventing diseases: The first advantage of raising turtles in green water is to prevent diseases. Although green water looks dirty and not very clear, it is Chlorella that actually causes it to turn green. This algae can release oxygen after photosynthesis, thus improving dissolved oxygen in water and inhibiting twigs of anaerobic bacteria, thus playing a role in preventing diseases.

2. Prevent odor: It is inevitable that turtles will encounter odor, which is mainly due to the large excretion of turtles and the lack of water itself. However, after the algae in green water become a part of the ecological cycle, the feces can be absorbed after being decomposed, thus avoiding its odor.

3. Provide shelter: Turtles generally don't like the environment with too strong light, and the green water itself is opaque, which provides it with certain shelter. In such an environment, it can grow more safely and enhance its wildness.
