Boyu Ceramic Rings

The hollow and permeable CR-300 ceramic rings are the best biochemical filter media to guard against harmful ammonia and nitro acid by providing the perfect environment for beneficial bacteria to grow. | These large colonies of beneficial bacteria, in conjunction with the porous ceramic rings, ensure a stable chemical water environment. With its composition of ceramic and active carbon, the ceramic rings allow for maximum oxygenation and water flow, promoting the growth of beneficial bacteria inside and outside the rings. These rings cause aerobic nitrification and anaerobic denitrification which create conditions similar to the natural environment of original micro-organisms. | Suited for all filter systems in a seawater or freshwater fish tank, the ceramic rings will optimise nitrobacteria growth, maximise filtration capacity, clean and deodorise your aquarium. | The biochemical ceramic rings offer a phytocide function that will keep your aquarium healthy. | | * Beneficial bacteria growth | * Kills ammonia and nitrates | * Suita all filter systems | * Porous and hollow for maximum water flow and oxygenation | * Aerobic nitrification and anaerobic denitrification | * Outer diameter: 12 mm | * Inner diameter: 4 mm | * Height: 11 mm | * Different size packs | * CR-300: 300 g
