If you want to mute the sewer pipe of the fish tank, you can make it smaller, or consider lengthening the pipe and diverting water. The downcomer is a part of the filter. The water is pumped into the filter by the submersible pump. After passing through layers of filter materials, it is discharged by the downcomer. Usually, the noise it produces is caused by the impact of water flow, so it can be padded with sponge at the bottom, which can also play a role in reducing noise.
is needed for the fish tank? 1. Filter: The filter is an essential equipment for the fish tank. Its function is to maintain the water quality. Good filtration can keep the water longer, which is also very beneficial to the health of fish. It is usually divided into three parts: physical filtration, chemical filtration and biological filtration, which need to use filter cotton, activated carbon, bacterial house and other filter materials.
2. Oxygen pump: The role of oxygen pump is also very important for fish tanks with high feeding density. It can continuously add oxygen to the water, thus improving the overall dissolved oxygen, which is conducive to the breathing of fish, and can also play a role in maintaining water quality, which is conducive to the reproduction of nitrifying bacteria and inhibiting anaerobic bacteria.
3. Heating rod: The heating rod is mainly aimed at tropical fish. Because they have certain requirements for water temperature, they need this kind of heating equipment. It also has the effect of temperature control. It can keep the water temperature at 20 ℃ or even higher, which is beneficial to the growth of fish.
