## Summary description

AquaNatura Quartz Bacteria House S is a filtration media designed for aquarium and pond filters. Each cylindrical unit measures 90×25 mm; the package contains 10 pieces.

## Long description

AquaNatura filtration media Quartz Bacteria House S 90×25 mm pack of 10 is a cylindrical biological filter media for aquarium and pond filters. Each piece measures 90 × 25 mm and is made from quartz-based material designed to provide extensive surface area for the colonization of nitrifying bacteria. The media supports biological filtration processes that help lower ammonia and nitrite levels and contribute to clearer, healthier freshwater environments.
Advantages
The quartz construction offers a durable, inert surface that does not alter water chemistry while providing a high surface-to-volume ratio for bacterial growth. The compact cylindrical shape and uniform dimensions allow easy placement in filter chambers, sponge filters, and media baskets. The media is suitable for repeated use after gentle cleaning and encourages efficient biological filtration that stabilizes water parameters in aquariums and garden ponds.
Suitable for
 Freshwater aquariums requiring biological filtration support
 Garden ponds and small water features with mechanical and biological filter systems
 Filter cartridges, media baskets, and canister filters where compact cylindrical media fits
 Systems focused on reducing ammonia and nitrite through beneficial bacteria colonization
Key specifications
 Material: quartz-based filtration media
 Shape and size: cylindrical units, 90 × 25 mm each
 Quantity: pack contains 10 identical units
 Function: designed to maximize surface area for bacterial colonization and biological filtration
 Compatibility: suitable for freshwater filter setups and most media compartments
How to use
Rinse the units briefly with dechlorinated water or aquarium water before first use to remove loose dust. Place the cylinders in the filter chamber, media basket, or canister so that water flows evenly around them to promote contact with beneficial bacteria. Maintain regular maintenance by inspecting the media periodically; if clogging occurs, perform gentle rinsing in aquarium water to preserve bacterial colonies. Replace only when structural degradation is evident or when biological performance can no longer be restored by cleaning.
Usage recommendations
Integrate the Quartz Bacteria House units as part of a layered filtration scheme combining mechanical pre-filtration and biological media. Avoid aggressive cleaning with tap water containing chlorine and limit mechanical squeezing to retain established nitrifying bacteria. Monitor ammonia and nitrite levels after installation and during maintenance to ensure effective biological filtration.
