## Summary description

AquaNatura Far Infrared Technology Ring filter media are white ring-shaped ceramic/porous media sized 17×21 mm, supplied in a 10 kg pack. Designed for aquarium and pond filtration, these rings increase biological surface area for beneficial bacteria, support mechanical debris trapping and help maintain water quality. Suitable for canister, sump and internal filters.

## Long description

AquaNatura Far Infrared Technology Ring white 17×21 mm are ceramic porous filter media supplied in a 10 kg pack, designed for aquarium and pond filtration. The rings measure approximately 17×21 mm and provide an expanded surface area to promote colonisation by nitrifying and denitrifying bacteria. Their porous structure supports biological filtration while also contributing to mechanical trapping of suspended particles. The product is compatible with canister filters, sumps and many internal filter housings and is intended to help maintain stable water parameters in freshwater and pond systems.
Advantages
These white Far Infrared Technology Rings combine a high-porosity ceramic matrix with a ring shape that increases contact area for biofilm formation. The material is chemically inert and stable in typical aquarium and pond environments. By offering a large internal and external surface area in a compact volume, the rings improve the efficiency of biological filtration and contribute to clearer water through mechanical particle retention. Supplied in a bulk 10 kg pack, they are suitable for establishing or replenishing media in medium to large filtration systems.
Suitable for
Canister filters in aquaria
Sump filters and filtration units in ponds
Internal filter housings with media baskets
Biological filtration upgrades or media replacement
Key specifications
Shape: ring
Color: white
Material type: porous ceramic/ceramic-based media
Individual ring size: approximately 17 × 21 mm
Pack weight: 10 kg
Function: biological and mechanical filtration support
Surface structure: high internal porosity for bacterial colonisation
How to use
Rinse the media briefly with dechlorinated water before first use to remove any dust or fine particles from manufacturing. Place the rings into the media basket or chamber of a canister, sump or internal filter ensuring even distribution to allow unrestricted water flow through the porous structure. For best results, combine with coarse mechanical pre-filter media to prevent rapid clogging by large debris. Monitor water flow and rinse or replace suitable amounts of media as part of routine maintenance when mechanical clogging reduces circulation.
Usage recommendations
Use the 10 kg pack to fill media chambers according to the volume of your filter; avoid overpacking to maintain water flow. Pair with mechanical filtration stages and regular maintenance to preserve biological activity. When introducing to a new system, allow several weeks for bacterial colonisation before relying solely on these rings for nitrification.
