There is noise at the air inlet of the aquarium, so it is impossible to increase oxygen if it is blocked. How to solve it?
There is basically no way to vibrate the pump body, but the general manufacturers will do the vibration reduction of the pump body, so the strength will not be too great. The main noise source of air pump, especially in fish tank, will be more obvious. Adding an expansion band to the air outlet can slightly suppress this sound, but it has limited effect on high-frequency components (dadada).
However, noise can also be reduced by installing silencers. Some put the filter cotton in the sewer to reduce the darkness, so it is too much trouble to clean the filter cotton. Some of them can also reduce the sound of running water by adding silencers. Another way is to close the water valve of the sewer pipe properly to reduce the water level difference of the sewer pipe. This is to slowly adjust the water valve until you can't hear the sound of running water.
There are other solutions, such as putting filter cotton in the sewer pipe, which can reduce the darkness, so cleaning the filter cotton is too troublesome. Some of them can also reduce the sound of running water by adding silencers. Another way is to close the water valve of the sewer pipe properly to reduce the water level difference of the sewer pipe. This is to slowly adjust the water valve and then adjust it until there is no noise. The circulating pump itself is not noisy, and it will vibrate and hum when it touches the filter box. In this way, a sponge can be placed under the filter pump to reduce vibration. It is best to put a damping block under the filter box, which can greatly reduce the hum of the filter pump.
If you are not a professional, you can adjust it with silencing cotton. But it is best to find a manufacturer or a merchant to ask how to solve it. After all, people are professionals in this field.
