## Long description

AquaNatura Far Infrared Technology Ring white 17×21 mm, 20 kg are white ring-shaped filtration media designed for aquarium and pond filtration systems. Each ring measures approximately 17×21 mm and the 20 kg packaging provides a high-volume supply for biological and mechanical filtration. The rings offer a structured surface area to support colonization by beneficial bacteria and contribute to maintaining stable water parameters in canister, biological and trickle filters.
Advantages
The ceramic-like rings combine a porous surface with regular geometry to ensure efficient water flow and improved contact between water and biofilm. Far infrared technology is integrated into the material to support a stable microenvironment for nitrifying bacteria. The white finish helps to visually assess media condition during maintenance and the uniform size simplifies packing and distribution inside filter chambers. High bulk quantity in a single pack reduces the need for frequent replenishment in larger systems.
Suitable for
Canister filters in freshwater and saltwater aquariums
Biological filters for ponds and outdoor systems
Trickle and wet/dry systems requiring high surface area
Large-volume filtration setups where media longevity and stability are needed
Key specifications
Form: open ring-shaped media with central hole for water circulation
Dimensions per ring: approximately 17×21 mm
Color: white
Material features: porous surface with Far Infrared Technology embedded in the matrix
Pack weight: 20 kg suitable for large filter volumes
Function: mechanical support and biological surface area for beneficial bacteria
How to use
Rinse the rings under clean tap water to remove dust from packaging before placement. Place the media into the filter compartment according to the filter manufacturer’s layout, ensuring unrestricted water flow through and around the rings. For canister filters, use a mesh bag or dedicated media basket to keep the rings contained and to facilitate removal during maintenance. Avoid compacting the media tightly; maintain loose packing to maximise contact between water and biofilm. When replacing media, stagger changes to preserve established bacterial colonies and avoid sudden shifts in biological load.
Usage recommendations
Monitor water parameters regularly after installation and during routine maintenance. Replace or top up media gradually rather than replacing the entire volume at once to maintain biological stability. In systems with heavy bioload, combine these rings with mechanical pre-filtration to reduce clogging and extend service intervals.
