Filter Media AquaNatura 3DM Five-color 18×15 mm granules, 0.5 kg

AquaNatura 3DM Five-color 18×15 mm granules are a multicolored filter media supplied in a 0.5 kg pack for aquarium filtration systems. The granules are intended for placement in mechanical and biological filter compartments to increase surface area for colonization by nitrifying bacteria while also helping to trap suspended particulate matter. The product is compatible with freshwater and saltwater aquaria and can be used in canister filters, hang-on filters, and sump systems to improve overall water quality and support stable biological filtration.

Advantages

The five-color granules combine a porous structure with a uniform granule size of approximately 18×15 mm, providing consistent flow and even distribution of water through the media. Their multicolored appearance allows easy visual identification during maintenance, while the particle geometry balances mechanical trapping of debris with space for microbial growth. The 0.5 kg pack offers a compact quantity suitable for topping up existing filter media or filling smaller chambers in multi-stage filtration setups.

Suitable for

• Home freshwater aquariums
• Marine and saltwater aquarium systems
• Canister filters and multi-stage filter cartridges
• Hang-on-back filters and filter baskets
• Sump compartments and custom filtration modules

Key specifications

• Granule size: approximately 18×15 mm
• Pack weight: 0.5 kg
• Material type: porous filter media granules suitable for biological colonization
• Color: five-color multicolored granules for visual identification
• Intended use: mechanical and biological filtration support
• Compatibility: freshwater and saltwater aquaria

How to use

Rinse the granules briefly with dechlorinated water before first use to remove dust from packaging. Place the AquaNatura 3DM Five-color granules into the mechanical or biological compartment of the filter so that water flows evenly through the media bed. Avoid packing the granules too tightly; allow sufficient space for water circulation and bacterial colonization. Replace or top up the media as part of regular filter maintenance, observing biological stability after changes.

Usage recommendations

For optimal biological filtration, combine these granules with other media types (mechanical pads or finer biological media) to create a staged filtration system. Monitor ammonia, nitrite and nitrate levels after installation and follow standard aquarium maintenance intervals to preserve effective nitrifying bacterial colonies.
