Nongfu Spring can raise fish. The PH value of Nongfu Spring is relatively stable and the water quality is good. It is also rich in mineral components, belonging to weakly alkaline water, which is suitable for fish farming and will not cause harm to fish. Pay attention to adjusting the water temperature when raising fish, and also need to adjust the indoor temperature. At the same time, it is beneficial to the growth and development of fish by regularly blowing oxygen or changing water. Nongfu Spring is produced in Qiandao Lake, which itself is a paradise for fish. Open containers (large bowls) can be used. The key is the oxygen content in the water. As long as there is enough oxygen, you can feed it. Water itself will be oxygenated under the action of atmospheric pressure, but fish will be consumed. Then it is a question of oxygen balance. Too many fish will die if they are not oxygenated in time.
