or not depends on the turbidity of the water body. When the transparency of the fish tank water is reduced, it is necessary to consider changing the water. It should be noted that the new water to be changed must be dried, so as to remove the chlorine in the water, so as to avoid adverse effects on the health of fish. The temperature before and after changing water should be consistent, and the difference should not exceed 2 degrees Celsius, otherwise it will stimulate fish.
of changing water? 1. Improving water quality: The primary benefit of changing water is to improve water quality. Because the water will age, although it looks clear, it contains harmful substances such as ammonia nitrogen, which is very harmful to the health of fish. Therefore, regular water change can reduce the content of ammonia nitrogen, but also clean up the dirt in the water, so as to make the water safer.
2. Disease prevention: If the water is not changed for a long time, the number of harmful bacteria will gradually increase, thus increasing the possibility of fish getting sick. Regular water change can prevent diseases, not only reduce the content of harmful substances in old water, but also inhibit the growth of new water.
3. Increase the dissolved oxygen: Regular change of water can also play a role in increasing the dissolved oxygen. The increase of dissolved oxygen in water is also helpful to the breathing of fish. However, if the oxygen consumption of fish is relatively high, it is not enough to increase oxygen by changing water, it is better to equip with oxygen pumps.
