In this way, the water can be extracted from the cylinder through the siphon principle. It should be noted that when pumping, be careful not to suck the fish at the bottom.
in the fish tank 1. Water change cycle: The water change cycle is generally related to the maintenance of water quality. If you usually feed less, maintain good water quality, or the fish tank is relatively large, holding a lot of water, water is not easy to break, you can change once a week or two. If the water is cloudy in a few days, it needs to be changed a little more frequently. In addition, according to the cycle of water exchange, the amount of water exchange should be well controlled. If you change the water frequently, you can change less. If you are lazy, you can change more.

3. Precautions: Do not change the water in the fish tank by force, otherwise the water quality will fluctuate and the fish will be stimulated. At the same time, the temperature of new water and old water should be close, and the difference between them should not exceed 2 degrees Celsius, so as to avoid too much change in water temperature and affect the health of fish.
