This introduction will focus on sponge filters, a highly efficient filtering device that is popular in small fish tanks. Sponge filters, also known as water fairy filters or pneumatic filter sponges, rely on their unique working principle to not only promote the circulation of water bodies, but also achieve efficient physical and biological filtration, creating an ideal living environment for aquatic organisms.
1.Basic structure of sponge filters
The structure of sponge filters is simple but efficient, and mainly consists of three parts: the main structure, filter cotton and air pump. The main structure is light and compact, which is easy to attach to the wall of the aquarium and save space. Filter cotton, as the core filter material, is built into the filter and is responsible for capturing and retaining impurities in the water. The air pump continuously delivers air to the filter through the air pipe, generating a large number of fine bubbles, which are the key to driving the water lifting effect.
2.Working principle of pneumatic filters
The working principle of sponge filters is based on the water lifting effect generated when bubbles rise. After starting the air pump, air enters the filter through the hose, generating continuous bubbles. When these bubbles rise in the water, they drive the surrounding water to rise due to the density difference, forming a significant water lifting effect. As the bubbles continue to rise, the water in the aquarium can continue to circulate. During the circulation process, the water flows through the filter cotton layer. The fine structure of the filter cotton can effectively absorb impurities such as suspended matter and organic matter to achieve physical filtration; at the same time, the bacteria attached to the cotton layer can also decompose organic matter, complete the biological filtration process, and convert harmful substances into harmless or low-harm substances.
3.Advantages of pneumatic filters
High efficiency and energy saving: The sponge filter uses the natural water rise caused by the rise of bubbles for filtration, without the need for additional power equipment, showing the characteristics of high efficiency and energy saving.
Wide application: It has a simple structure, convenient operation, and low cost. It is especially suitable for small fish tanks and occasions that require auxiliary filtration. Whether it is a home fish enthusiast or a commercial aquarium, you can find a suitable choice.
Oxygenation effect: The rising bubbles not only lift the water body, but also have an oxygenation effect. The oxygen released when the bubbles burst increases the dissolved oxygen content in the water, providing a more sufficient oxygen environment for aquatic organisms.
Easy maintenance: The filter cotton of the sponge filter can be easily removed for cleaning or replacement to maintain its excellent filtering effect. When cleaning, just rinse with clean water, no chemical cleaning agents are needed, and maintenance is simple and quick.
Through the above analysis, we can have a deeper understanding of the charm of the sponge filter. It is not only an indispensable filtering equipment in the aquarium, but also a powerful assistant in creating a healthy aquatic environment.
