## Summary description

AquaNatura 3DM Beneficial Bacteria House is a granular filter media (15×20 mm) supplied in a 10 kg bag for aquarium and pond biological filtration. Designed to provide high surface area for colonization of nitrifying bacteria, it supports effective biological filtration, ammonia and nitrite reduction, and improved water clarity in freshwater systems and planted tanks.

## Long description

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.
