## Summary description

AquaNatura 3DM Nine Hole filter media, packed 0.5 kg, consists of shaped 47×35 mm elements with nine holes for mechanical and biological filtration in aquariums and small ponds. Designed to increase surface area for beneficial bacteria and improve water clarity; suitable for internal and external filter cartridges and media beds.

## Long description

AquaNatura 3DM Nine Hole filter media is a pack of shaped porous elements sized 47×35 mm and supplied as 0.5 kg of material. Each element contains nine through-holes and a textured outer surface to increase effective surface area for biofilm development. The product is intended for mechanical pre-filtration and to support biological filtration by providing space for beneficial nitrifying bacteria, improving water clarity and stability in aquariums and small garden ponds. The compact format makes it compatible with many internal and external filter cartridges and media beds.
Advantages
The nine-hole design and textured surfaces offer a high surface-to-volume ratio that helps establish and maintain colonies of nitrifying bacteria while allowing water to flow freely through the media. The uniform element size (47×35 mm) and the 0.5 kg package simplify replacement and dosing into filter chambers. Made for mixed mechanical and biological use, the media reduces suspended particles and supports biological ammonia and nitrite conversion without adding chemical agents to the water.
Suitable for
 Home aquariums requiring biological filtration support
 Small outdoor ponds and water features with low to moderate bioload
 Internal and external filter cartridges and modular media baskets
 Media beds and polishing stages where increased surface area is needed
When it may not be suitable
This filter media is not a chemical filter and will not remove dissolved organic compounds, heavy metals, or discoloration caused by dissolved substances; additional specific media may be required for those tasks. It is designed for small to medium filtration setups; very large systems or heavily stocked public aquaria may need higher-volume or denser media solutions for adequate biological capacity.
Key specifications
 Element shape: rectangular/rounded elements with nine through-holes
 Element dimensions: approximately 47 × 35 mm
 Pack weight: 0.5 kg
 Function: mechanical and biological filtration support
 Material properties: porous, textured surface for bacterial colonization
 Compatibility: suitable for internal and external cartridge filters and media baskets
How to use
Rinse the media briefly in aquarium or pond water before first use to remove dust from manufacturing and packaging. Place the elements evenly in a filter cartridge, media basket, or media bed so that water flows through the holes and across the textured surfaces. For biological seeding, include the media in an established filter or transfer a small amount of matured bio-media from an active aquarium to accelerate colonization. Replace or top up the media gradually during maintenance to avoid disturbing the established bacterial colonies.
What to consider before purchase
 Confirm physical dimensions and available space in your filter housing to ensure elements fit correctly
 Assess whether you also need chemical media (e.g., activated carbon) for dissolved contaminants
 Determine the volume of media required for your aquarium or pond’s bioload and flow rate
Usage recommendations
Use AquaNatura 3DM Nine Hole as part of a multi-stage filtration approach: combine mechanical pre-filtration, this biological media for nitrification, and targeted chemical media where needed. Maintain steady water flow through the media and avoid full replacements at once—replace portions gradually to preserve beneficial bacteria.
