10W oxygen pump is generally used for 1.2m fish tank. However, this is not absolute, but also related to the density of fish. If the number of fish is not large, 2.5-5W oxygen pump is more than enough, if the breeding density is relatively large, the oxygen consumption of fish will increase, it needs a slightly larger power, usually 10-15W oxygen pump is enough.
1, too many fish: As mentioned above, the more the number of fish, the greater the oxygen consumption, so it will lead to fish hypoxia. In addition to using an oxygen pump to pump oxygen, you can also consider reducing a few fish, or changing a larger tank. Of course, different types of fish sometimes affect oxygen consumption.
2. The temperature is too high: The dissolved oxygen in the water itself is limited, but in the case of continuous high temperature weather, the temperature will drive the water temperature to rise, which will lead to a decrease in dissolved oxygen, and the fish will also lack oxygen. Therefore, we must avoid putting the fish tank in a room where the temperature is too high, and it is better to turn on the air conditioner to cool down in summer.
3. Fish tank algae explosion: If the water is not changed in time at ordinary times, and too much bait is thrown into the tank at the same time, the fish tank algae explosion will be caused. Algae blooms also compete for oxygen, starving the fish of oxygen. In view of this situation, in addition to timely cleaning, but also in peacetime to reduce feeding, and it is best to avoid light.
