The reason why fish farming in well water is easy to die is that the temperature difference between the newly pumped well water and the ambient temperature is too great. When such water is poured into the fish tank, it will immediately cause the water temperature to change, which is most likely to cause the stress reaction of the fish, which will lead to its discomfort or even death. Therefore, it is necessary to let the water stand for a period of time and wait until its temperature and temperature are close before adding it to the fish tank.

Well water is groundwater, which is usually infiltrated slowly by surface water. In this process, many metal ions will be adsorbed, so the content of calcium ions and magnesium ions is generally high, and the hardness of water body is also very high. You know, too hard water can't raise fish, so it must be filtered and other methods to clean up the impurities inside.

Because the well water itself can't contact the air, the oxygen content in the water body is very low. In order to reduce the hardness, some methods used will also lead to further decrease of dissolved oxygen, and too little oxygen can't raise live fish. In order to make fish survive better, it is necessary to use oxygen pump to supply water with oxygen. Generally, it takes several hours to explode oxygen to improve the situation of oxygen shortage, or oxygen enhancer can be used to increase oxygen.

Groundwater will also be polluted, and once pollution occurs, it is difficult to control it. Therefore, it is best not to use well water to raise fish. Generally, it is better to use tap water to raise fish. Such water is suitable for fish survival only after being trapped.
