Filter media AquaNatura 3DM Octagonal filter material 88×38 mm, 20 kg

AquaNatura 3DM Octagonal filter material 88×38 mm, 20 kg is a bulk filter media designed for biological and mechanical filtration in aquariums and garden ponds. The media consists of octagonal-shaped pieces with dimensions of 88×38 mm supplied in a 20 kg bag. Its open structure and specific geometry provide a large surface area for colonization by nitrifying bacteria while allowing efficient water flow through filter chambers, resulting in improved water clarity and stable biological filtration.

Advantages

The octagonal shape and consistent size ensure uniform packing and predictable flow characteristics, reducing channeling and dead zones inside the filter. The choice of a robust, inert material provides long service life without degrading water chemistry. Supplied in a 20 kg bulk bag, the media is suitable for large filters and multiple filter chambers, enabling scalable use across aquarium and pond systems. The geometry optimizes surface-to-volume ratio to support high bacterial load and effective mechanical trapping of larger particles.

Suitable for

• Freshwater and saltwater aquarium biological filtration
• Pond filter systems for gardens and water features
• External canister filters and multi-chamber filtration units
• Situations requiring high surface area media for nitrification

Key specifications

• Media shape: octagonal pieces
• Piece dimensions: approximately 88 × 38 mm
• Pack size: 20 kg bulk bag
• Material type: inert filter media (non-reactive composition)
• Function: combined biological and mechanical filtration
• Flow characteristic: open structure for efficient water passage

How to use

Rinse the media briefly with dechlorinated water before introduction to remove dust from packaging. Place the AquaNatura 3DM Octagonal media into the designated biological or mechanical chamber of the filter, ensuring even distribution to avoid gaps and channeling. Use layered arrangements when combining with finer mechanical filter pads or coarse media: coarse mechanical layers should precede biological media in the direction of water flow. After installation, monitor water parameters and ammonia/nitrite levels until biological equilibrium is established.

Usage recommendations

For optimal biological performance, seed the media with established filter material when cycling a new system or replacing large portions of existing media. Periodically inspect and gently clean the media with aquarium water during maintenance to remove excess debris while preserving beneficial bacterial colonies. Replace only when physical degradation or persistent clogging reduces flow and filtration efficiency.
