Use to increase surface area for beneficial bacteria, improve water clarity, and support efficient flow through filter chambers.

## Long description

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.
