Boyu Ceramic Rings

Protect your fish tank against nitrates and ammonia with the Boyu Ceramic Rings which provide the ideal environment for the growth of beneficial bacteria colonies.

The highly porous and hollow ceramic rings effectively increase the flow of water and distribution of oxygen. Made from ceramic and soft active carbon, the rings ensure a chemically stable, healthy aquarium and allow for the beneficial bacteria to grow inside and on top of its surface. The rings have a phytocide function to protect and create an environment for beneficial bacteria which is similar to micro-organisms’ natural habitat.

These ceramic rings are the best filter media for ensuring the growth of nitrobacteria, optimization of the filtering process and cleaning and deodorizing of your fish tank. These multi-function ceramic rings are great for use in a freshwater or saltwater aquarium.
