## Summary description

AquaNatura Far Infrared Technology ring media for aquarium filtration, red, size 17×21 mm, supplied in a 20 kg pack. Designed as mechanical and biological filter media to increase surface area for beneficial bacteria, improve water flow and support biological filtration. Suitable for use in internal and external canister filters and other media chambers.

## Long description

AquaNatura Far Infrared Technology media rings are red, 17×21 mm ceramic filter rings designed for aquarium filtration systems. Supplied in a 20 kg pack, these rings serve as both mechanical and biological media, providing increased surface area for colonisation by beneficial nitrifying bacteria while maintaining open channels for effective water flow. Compatible with internal and external canister filters and other media chambers, the rings are intended to support stable biological filtration and clearer aquarium water in freshwater and marine setups.
Advantages
The porous ceramic composition and ring shape maximise surface area per volume, encouraging rapid establishment of biofilm and nitrifying bacteria responsible for ammonia and nitrite conversion. The red colour and Far Infrared Technology treatment are integrated into the ceramic structure without affecting water chemistry. The 17×21 mm size balances packing density with water circulation, reducing clogging while maintaining contact time for biological processes. A 20 kg pack provides bulk supply for large filters, multi-filter systems or repeated media replacements.
Suitable for
Internal aquarium filters that accept loose media
External canister filters and media chambers
Biological filtration in freshwater and marine tanks
Large-volume systems and multi-tank setups requiring bulk media
Key specifications
Material: porous ceramic with Far Infrared Technology treatment
Colour: red
Individual ring dimensions: approximately 17 mm inner diameter × 21 mm outer diameter
Intended functions: mechanical trapping of debris and biological colonisation surface
Pack weight: 20 kg bulk package
Form: loose rings suitable for media baskets and chambers
How to use
Rinse the media briefly in dechlorinated or tank water to remove dust before first use. Place the rings in a suitable media basket, chamber or directly into the filter compartment where loose media is acceptable. Distribute evenly to maintain open water channels and avoid overly compact packing that restricts flow. Monitor flow rate and water clarity after installation; adjust quantity or arrangement if flow is reduced. Replace or refresh a portion of the media during routine maintenance to remove accumulated detritus while preserving established bacterial colonies.
Usage recommendations
Use together with mechanical pre-filtration to reduce clogging and maintain performance. When starting a new tank or after cleaning, seed the media with established filter material or use an ammonia source to accelerate bacterial colonisation. Do not attempt to sterilise the media with high-temperature methods or strong chemicals, as this will destroy beneficial bacteria and may damage the ceramic properties.
