To increase the suction of the overflow area, you can increase the height of the water level plate, which can reduce the water carrying capacity, thereby increasing the water surface, or adjust the direction of the water outlet. Of course, the simplest way is to improve the power of the pump, but the power can not be too high, otherwise it will lead to excessive water speed, which is harmful to the health of fish.
1. Put a sponge: The noise in the overflow area is mainly generated when the water falls. In view of this situation, the best way is to put a sponge at the water outlet. In this way, when the water flows through the sponge, it can have a buffering effect, thereby reducing the volume of the noise.
2. Extend the drainage pipe: The length of the drainage pipe will also affect the noise level. Generally, the shorter the drainage pipe is, the louder the noise will be, while the longer the drainage pipe is, the smaller the noise will be. Therefore, in view of the relatively short drainage pipe, you can extend it, or change a longer drainage pipe.
3. Raise the water level: If the water level of the overflow is relatively high, it is equivalent to shortening the drop of the water flow and reducing the noise. Of course, in addition to raising the water level, as long as it can reduce the impact of water flow, it can reduce noise.
