Filter Media AquaNatura 3DM Beneficial Bacteria House 15×20 mm 10 kg

AquaNatura 3DM Beneficial Bacteria House is a granular biological filter media supplied in a 10 kg bag, with individual granules sized approximately 15×20 mm. Engineered to provide an extensive surface area for colonization, this media supports the growth of nitrifying bacteria that convert ammonia and nitrite into less harmful compounds. It is intended for use in aquarium and pond filtration systems where biological stabilization and water clarity are priorities.

Advantages

The granular structure of AquaNatura 3DM offers a large internal and external surface area that facilitates rapid bacterial colonization and effective biological filtration. Its uniform grain size ensures consistent water flow through the media bed, reducing channeling and maintaining contact between water and biofilm. Supplied in a 10 kg bag, the product is convenient for filling canister filters, external biofilters, and pond filter chambers. It is chemically inert and designed for long-term use without releasing substances that could affect water chemistry.

Suitable for

• Freshwater aquariums, including planted and community tanks
• Garden ponds and outdoor biological filtration systems
• Canister filters, external biofilters and filter chambers
• Systems requiring increased nitrification capacity and improved water clarity

Key specifications

• Granule size: approximately 15×20 mm
• Form: granular media
• Weight per pack: 10 kg
• Intended function: biological filtration and support for nitrifying bacteria
• Suitable for: freshwater systems and planted tanks
• Chemical behavior: chemically inert under normal aquarium conditions

How to use

Rinse the media briefly with dechlorinated water to remove dust before initial use. Place the granules in the filter chamber or media basket ensuring even distribution and stable flow through the media. For optimal biological colonization, introduce the media into an established filter where beneficial bacteria are present, or allow several weeks for bacterial populations to develop when used in new systems. Do not wash the media with chlorinated tap water or expose it to disinfectants during maintenance; instead, perform gentle rinses using aquarium or pond water if cleaning is necessary.

Usage recommendations

For effective nitrification and consistent water quality, combine AquaNatura 3DM with mechanical filtration upstream to remove particulates and perform regular partial water changes. Monitor ammonia, nitrite and nitrate levels during initial colonization, and replace only a portion of the media at a time if full media renewal is required to preserve established bacterial colonies.
