Filter media AquaNatura 3DM Octagonal Filter Material 88×38 mm 10 kg

AquaNatura 3DM Octagonal Filter Material 88×38 mm 10 kg is a granular aquarium filter media with octagonal particles designed to support mechanical and biological filtration in both freshwater and marine systems. The media's octagonal shape and 88×38 mm particle size provide an increased surface area that encourages the growth of beneficial nitrifying bacteria while mechanically trapping suspended debris. Supplied in a 10 kg pack, this filter material is intended for use in canister and internal filters where durable, high-surface-area media are required to improve water clarity and biological stability.

Advantages

The octagonal geometry of the AquaNatura 3DM media increases usable surface area compared with spherical granules, supporting biofilm formation and efficient nitrification. Its granular form allows water to flow through evenly, providing both mechanical retention of particulate matter and long-term biological filtration. The 88×38 mm particle size balances flow resistance and contact area to reduce clogging while maintaining effective filtration performance. Packaged in a 10 kg quantity, it is suitable for larger filter loads and periodic media replacement.

Suitable for

• Canister filters in freshwater and marine aquaria
• Internal aquarium filters requiring granular media
• Systems that need combined mechanical and biological filtration
• Setups where increased media surface area is desired for nitrifying bacteria

Key specifications

• Particle shape: octagonal granules
• Particle size: 88 × 38 mm
• Function: mechanical and biological filtration
• Pack weight: 10 kg
• Compatibility: suitable for freshwater and marine aquarium filtration systems

How to use

Rinse the AquaNatura 3DM filter material under tap water until runoff is clear to remove dust from packaging. Place the granules into the media compartment of a canister or internal filter, ensuring even distribution to allow unobstructed water flow. Use appropriate retention pads or media baskets if required by the filter design to prevent particle migration. Replace or refresh the media periodically according to bioload and water quality measurements; do not sterilize the media to preserve established beneficial bacteria.

Usage recommendations

For best results, combine AquaNatura 3DM with coarse mechanical pre-filtration to extend service intervals. Monitor ammonia, nitrite and nitrate levels after installation to confirm biological activity. When replacing media, exchange portions gradually to maintain stable bacterial colonies and avoid sudden shifts in water chemistry.
