Aquarium fish can't live without water, water can't live without aquarium, and the water in aquarium can't live without filter equipment!

The filtration system is a necessary equipment in the Aquarium. A clear understanding of filtration equipment and equipment, and how to stabilize the filtration system and make it truly useful, is often a major problem for beginners.

There are two ways to solve the waste in the Aquarium, one is to decompose it by bacteria, the other is to pump it out by changing water. The bacteria used to decompose waste grow on top of the filter equipment in the fish tank.

The filtration system includes two aspects, one is biochemical filtration, and the other is physical filtration.

Biochemical filtration: It is a filtration method mainly based on cultivating bacteria.

Our common ones are water monsters (pneumatic filters) and the popular air lift. The principle is to form a high oxygen zone and water fluid on porous filter materials to cultivate Nitrifying bacteria.

Physical filtration: It is used to extract visible waste from the cylinder.

By using a denser filter material, commonly known as filter cotton, it is used to block the return of large particles of waste into the cylinder. The physical filtration process also includes the biochemical filtration process, because Nitrifying bacteria will also grow on the filter cotton. The most common is upper filtration.
