## Summary description

AquaNatura Far Infrared Technology filter media rings for aquarium filtration, white, sized 17×21 mm, supplied in a 0.5 kg pack. Designed to provide mechanical support and biological surface area for beneficial bacteria while incorporating far-infrared material properties. Suitable for canister and internal filters to improve water clarity and biofiltration in freshwater and marine setups.

## Long description

AquaNatura Far Infrared Technology filter media rings are white, toroidal ceramic rings sized 17×21 mm supplied in a 0.5 kg pack for aquarium filtration. These rings combine traditional mechanical support and porous surface area for colonization by beneficial nitrifying bacteria with materials engineered to incorporate far-infrared properties. They are intended for use in canister and internal filters to support biological filtration and help maintain water clarity in both freshwater and marine aquaria.
Advantages
The ceramic ring geometry and porous structure provide a high specific surface area that promotes rapid bacterial colonization and stable biological filtration while retaining particulate matter. Incorporation of far-infrared technology aims to support microenvironment stability and may enhance nutrient exchange at the media surface. The compact 17×21 mm size fits most canister and internal filter baskets, and the neutral white color is compatible with aquarium setups where media visibility is a consideration.
Suitable for
 Biological filtration in freshwater aquariums
 Biological filtration in marine and reef aquaria (as part of a mixed-media approach)
 Use in canister, hang-on-back, and internal filter baskets
 Filtration systems requiring high surface area media for nitrifying bacteria
Key specifications
 Material: porous ceramic with far-infrared additive
 Shape: toroidal (ring)
 Dimensions: 17 × 21 mm
 Color: white
 Pack weight: 0.5 kg
 Function: mechanical support and biological surface for beneficial bacteria
How to use
Rinse the filter rings in dechlorinated or conditioned aquarium water before first use to remove dust from manufacturing. Place the rings in the filter basket or media compartment so water flows evenly through the media for optimal contact with the porous surfaces. For new aquaria, integrate these rings with established biological media to accelerate bacterial colonization; in established systems, replace or top up media gradually to avoid disrupting the biological filter. Monitor water parameters regularly after adding or changing media.
Usage recommendations
For best results, use the rings as part of a mixed-media filtration strategy combining mechanical, chemical, and biological stages. Avoid cleaning the rings with chlorinated tap water; use aquarium water to preserve beneficial bacteria. Replace or replenish media incrementally rather than all at once to maintain stable biological filtration.
