## Summary description

AquaNatura 3DM Nine Hole media filter gravel, 47×35 mm grain size, 10 kg pack.

## Long description

AquaNatura 3DM Nine Hole media filter gravel in 47×35 mm grain size is a granular filtration medium supplied in a 10 kg pack. Designed for aquarium and pond filtration systems, this media supports mechanical trapping of particles while offering a large surface area for colonization by nitrifying and denitrifying bacteria. Its medium-sized grains make it suitable for systems that require good water flow and efficient biological activity without excessive compaction.
Advantages
The media combines mechanical and biological filtration properties, capturing debris while providing extensive surface area for beneficial microorganisms. Its uniform 47×35 mm grain size ensures consistent water flow and reduced risk of channeling. Packaged in a 10 kg quantity, it is convenient for topping up or replacing media in canister filters, internal filters, trickle towers and bio-reactors. The granular structure supports oxygen exchange and stable bacterial colonization, contributing to improved water quality over time.
Suitable for
Canister and internal aquarium filters that accept medium-sized granular media
Trickle filters and wet/dry systems for biological filtration
Bio-reactors and fluidized beds requiring stable granular support
Pond filtration units where durable media with good flow characteristics is needed
Key specifications
Grain size: approximately 47 × 35 mm
Weight per pack: 10 kg
Material type: granular media designed for biological colonization and mechanical filtration
Intended use: aquarium and pond filtration systems
Flow behavior: permits good water circulation while minimizing compaction
How to use
Rinse the media thoroughly with dechlorinated water before first use to remove dust and fines. Place the gravel into the filter compartment, bio-reactor chamber or support baskets according to the manufacturer’s layout, ensuring even distribution for consistent flow. For canister and internal filters, position the media in a layer that allows water to pass uniformly without excessive channeling. Replace or top up media as part of regular maintenance when biological performance declines or when mechanical clogging reduces flow.
Usage recommendations
Monitor flow rate and water parameters regularly after installation; allow time for bacterial colonization before assessing full biological filtration performance. Avoid cleaning the media with chlorinated tap water and limit aggressive scrubbing to preserve established bacterial colonies. Combine with mechanical pre-filtration if heavy particulate load is expected to extend media lifetime.
