Filter Media AquaNatura 3DM Five-color 18×15 mm 10 kg – aquarium filter media granules

AquaNatura 3DM Five-color filter media are 18×15 mm granules supplied in a 10 kg bag for aquarium filtration. Designed to act as both mechanical and biological media, these multicolored granules offer a large surface area for colonization by beneficial bacteria while also trapping suspended particles. The media are suitable for use in canister filters, sumps and filter bags and can be integrated into freshwater and marine systems to help maintain water clarity and support stable biological filtration.

Advantages

The five-color granules combine physical filtration and biological support in a single media, allowing mechanical removal of debris and simultaneous development of nitrifying bacteria. Uniform 18×15 mm granules provide consistent flow-through and reduce channeling, while the robust material withstands regular rinsing and handling. Supplied in a 10 kg bag, the media are convenient for medium to large systems or for topping up existing filter volumes.

Suitable for

• Canister filters in home and hobby aquaria
• Sump filtration in reef and marine tanks
• Filter bags and media baskets for freshwater systems
• Pre-filtration and polishing stages to improve water clarity

Key specifications

• Granule size: approximately 18 × 15 mm
• Function: combined mechanical and biological media
• Colour: five-color mix for visual identification and even packing
• Packaging: 10 kg bag
• Compatibility: suitable for freshwater and marine aquaria

How to use

Rinse the granules gently with aquarium water or dechlorinated water before initial use to remove any dust generated during packaging. Place the media in a dedicated media basket, canister compartment or filter bag, ensuring good water flow through the packed bed to promote oxygenation and bacterial colonization. Use the media as part of a multi-stage filtration setup alongside mechanical pads and chemical media if required. Replace or top up the media progressively when a noticeable reduction in flow or accumulation of fine debris occurs; do not replace all media at once to preserve established biological colonies.

Usage recommendations

For best performance, maintain stable water parameters and avoid aggressive cleaning that would remove beneficial bacteria. Inspect and gently rinse the media during routine maintenance using tank water. Combine AquaNatura 3DM Five-color with mechanical pre-filters for prolonged service life and improved water clarity in both freshwater and marine systems.
