## Summary description

AquaNatura 3DM Octagonal is octagonal-shaped filter media designed for aquarium filtration. Dimensions 88×38 mm, net weight 0.5 kg. Intended to provide mechanical and biological support in filter systems, improving water clarity and promoting beneficial bacterial colonization. Suitable for use in external and internal aquarium filters and media chambers.

## Long description

AquaNatura 3DM Octagonal 88×38 mm filter media is an octagonal-shaped aquarium filtration material designed to support both mechanical and biological filtration. With dimensions of 88×38 mm and a net weight of 0.5 kg, this media provides surface area and internal channels that encourage colonization of beneficial nitrifying bacteria while trapping larger particles, contributing to clearer water in both freshwater and marine setups. The geometry of the pieces helps maintain water flow and prevents compaction inside media chambers and external canister filters.
Advantages
The octagonal shape and porous structure deliver a combination of mechanical particle retention and a large surface area for biofilm development, improving nitrification and reducing ammonia and nitrite levels over time. The individual pieces resist clogging and maintain flow distribution within media baskets, making them easy to rinse and reuse during routine maintenance. Compatibility with a range of external and internal filters and media chambers adds installation flexibility.
Suitable for
 External canister filters with media baskets
 Internal box filters and media chambers
 Freshwater aquaria requiring biological filtration support
 Marine and reef systems where mechanical and biological filtration is needed
 Refugiums and sump chambers that require stable bio-media
When it may not be suitable
This filter media may not be appropriate for nano tanks or very small filters where the 88×38 mm pieces are too large to fit without modification. It is not a chemical filtration medium and will not remove dissolved organics, heavy metals, or odors by itself; a separate chemical media or polishing stage may be required for those purposes.
Key specifications
 Shape: octagonal pieces designed for flow-through contact
 Dimensions: 88 × 38 mm per piece
 Net weight: 0.5 kg
 Function: mechanical particle retention and biological surface for bacterial colonization
 Compatibility: suitable for external and internal aquarium filters and media chambers
How to use
Rinse the media briefly with aquarium water before first use to remove dust. Place the AquaNatura 3DM Octagonal pieces into the media basket, chamber, or a suitable mesh bag inside your external canister or internal filter, ensuring even distribution to maintain flow. During routine maintenance, rinse the media gently in removed aquarium water to preserve beneficial bacteria rather than using tap water or aggressive cleaning. Replace small amounts periodically if pieces show excessive wear, but do not replace all media at once to avoid disrupting established biological colonies.
What to consider before purchase
 Check internal dimensions of your filter or media basket to ensure 88×38 mm pieces will fit
 Determine whether you also need chemical media (activated carbon, resins) for dissolved contaminants
 Consider required quantity for your filter volume; 0.5 kg is a modest pack for supplementary bio-media
 Plan for gentle rinsing during maintenance to preserve bacterial colonies
Usage recommendations
Use AquaNatura 3DM Octagonal as part of a multi-stage filtration setup: mechanical pre-filtering, followed by this biological media, and a final chemical or polishing stage if required. Maintain regular partial rinses with aquarium water and avoid complete simultaneous media replacement to keep biological filtration stable.
