ceramic ring is usually placed at the bottom of the filter, where the water flows last. The reason for this is that the water flow needs to pass through the physical filtration zone and the chemical filtration zone to filter out the impurities and dirt in the water, so as not to cause harm to the nitrifying bacteria, but also to reduce the possibility of blockage.
can be used without ceramic rings? 1. Bacteria house: Bacteria house is a common substitute. Its price is higher than ceramic rings. It is usually made of talcum powder. There are many holes on it, and the surface area is very large. Therefore, it is very suitable for the growth and reproduction of a large number of nitrifying bacteria. The overall shape is also very similar to the ceramic ring.
2. Biochemical ball: The biochemical ball is usually placed in the water, which can better play its role. It is made of plastic, and its shape is mostly spherical, but it is also square or irregular, with many bulges on it. It also has some disadvantages, such as limited scope of application, which can not be used in many filtering methods.
3. Biochemical cotton: Biochemical cotton has many pores, good water permeability, easy cleaning, and even physical filtration, so it is also a good substitute. However, it will contain some extra elements in the process of production, so it will often affect the water quality when it is placed in the filter.
