Ziss Aqua ZB-300 Moving Bed Filter
The ZB-300F is an air-powered aquarium filter designed to provide clean and healthy water in your aquarium. It is widely used in professional nurseries and is also known as a ‘Moving Bed Filter’. The filter media continuously move over each other, ensuring even and efficient filtration.
This filter supports the natural breakdown of waste products such as ammoniac, nitrate, and nitrite through organic processing. A large volume of air is introduced into the filter, which helps in degassing these compounds.
By promoting the removal of these substances, the ZB-300F helps maintain low Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) values, indicating effective water quality control.

FAQ
How does the moving bed mechanism improve filtration?
The filter media continuously move over each other, ensuring uniform contact between water and media, which enhances the efficiency of biological filtration and waste breakdown.
What types of waste products does the ZB-300F filter process?
The ZB-300F processes ammoniac, nitrate, and nitrite through organic conversion, helping maintain stable water chemistry.
Is the filter suitable for professional aquarium setups?
Yes, the ZB-300F is specifically used in professional nurseries and is designed for consistent, high-performance water treatment in demanding environments.
