Oxygen pump generally has noise, noise is caused by the vibration of the pump. The first problem to be solved is the swing of the connecting rod, and the noise can be reduced by adjusting the distance between the connecting rod magnet and the electromagnet. Secondly, the airbag movement, only need to block the air hole, the noise will be reduced. There is also the preparation of filter cotton, which is glued to the sound insulation of the air pump, or simply put something on the shell of the air pump for sound insulation.
1. Fish consume a lot of oxygen: There are many kinds of fish. Most small and medium-sized fish consume little oxygen, and can even survive in an environment with low dissolved oxygen. Therefore, they do not need to be specially equipped with an oxygen pump. However, if they are some large fish, they need a lot of oxygen. When the dissolved oxygen in water is low, it is easy to affect its survival, so oxygen pumps are needed.
2. More organisms in the tank: More organisms in the tank generally means that the breeding density is high, that is, more fish are raised, more fish are raised, and the oxygen consumption is high, so an oxygen pump is needed. But not only fish need oxygen pump, grass need oxygen pump, aquatic plants in addition to photosynthesis release oxygen, breathing will consume oxygen, at night need to use oxygen pump oxygen.
3. The water temperature is relatively high: usually, the dissolved oxygen content of the water body is inversely proportional to the water temperature, that is to say, the higher the temperature, the lower the dissolved oxygen content. Therefore, some tropical fish that like high temperature must be oxygenated with an oxygenation pump to keep them alive. Generally, when you are sick, you need to raise the temperature, so you also need to give oxygen.
