## Long description

AquaNatura 3DM Mineral Ring, red, 20×19 mm granules, supplied in a 20 kg bag, is a bulk filtration media intended for aquarium and pond filter systems. The media consists of uniformly shaped red mineral rings designed to increase available surface area for colonization by nitrifying and denitrifying bacteria while also providing mechanical support for particulate capture. Its granule size and shape make it suitable for installation in canister filters, trickle towers and sump chambers where stable biological filtration and improved water quality are required.
Advantages
The mineral ring media offers a high internal and external surface area that promotes fast establishment of beneficial biofilms and stable nitrification. Its robust mineral composition resists breakdown and maintains flow-through porosity under prolonged use. The uniform 20×19 mm granules provide predictable hydraulic behaviour and even distribution inside filter housings, reducing channeling and dead zones. Being a neutral-coloured red media, it is easy to inspect visually during routine maintenance.
Suitable for
 Canister filters in freshwater and pond systems
 Trickle and trickle-tower filters for continuous biofiltration
 Sump filters and wet/dry filter setups
 Bulk media chambers where high surface area is required
Key specifications
 Granule shape: ring-shaped mineral granules
 Granule dimensions: approximately 20 × 19 mm
 Color: red
 Package weight: 20 kg bag
 Function: biological and mechanical filtration support
How to use
Rinse the mineral rings briefly with dechlorinated water or well-conditioned aquarium/pond water to remove dust from manufacturing and transport. Place the granules into the designated media chamber of a canister, trickle, or sump filter, ensuring even distribution and allowing sufficient free flow between pieces. Avoid compacting the media tightly; maintain a loose bed to ensure water flow and oxygen access for bacteria. Monitor water parameters after installation and allow a colonization period for beneficial bacteria to establish before relying on full biological filtration capacity.
Usage recommendations
Use as part of a multi-stage filtration strategy: combine with mechanical pre-filtration to remove solids and with carbon or other chemical media if specific contaminant removal is required. Inspect media periodically for clogging and rinse gently in conditioned water when flow decreases. Replace only when structural degradation or irreversible fouling is evident.
