## Summary description

AquaNatura Quartz Bacteria House S filter media are porous quartz cylinders sized 90×25 mm sold in a pack of 20. Designed for aquarium and pond biological filtration, these media provide surface area for beneficial bacteria colonization to support nitrification and water clarity. Suitable for internal and external filters where cylindrical ceramic/quartz bio-media fit.

## Long description

AquaNatura Quartz Bacteria House S filter media are porous quartz cylinders, each measuring 90×25 mm, supplied in a pack of 20. Designed for aquarium and pond biological filtration, these cylinders provide a high surface area for colonization by nitrifying bacteria. Their cylindrical shape and uniform size make them compatible with many internal and external filter systems that accept cylindrical ceramic or quartz bio-media. The media support stable biological filtration, contributing to the breakdown of ammonia and nitrite and promoting clearer, healthier water.
Advantages
The porous quartz structure offers a durable, inert surface with extensive microporosity that encourages rapid bacterial colonization while resisting breakdown and leaching. Uniform dimensions and smooth edges simplify installation and arrangement inside filter chambers, ensuring consistent water flow and contact time. Sold as a pack of 20, these cylinders allow users to scale biological media volume to the size of the filtration unit or stocking levels in the aquarium or pond.
Suitable for
Freshwater aquariums requiring biological filtration and increased nitrifying bacteria surface area
Ponds with external filters that accept cylindrical bio-media
Internal canister and hang-on-back filters compatible with 90×25 mm cylinders
Filter setups where inert, long-lasting media are preferred to maintain water stability
Key specifications
Material: porous quartz
Shape: cylindrical
Dimensions: 90 mm length × 25 mm diameter
Pack quantity: 20 cylinders
Primary function: biological filtration (bacterial colonization surface)
Compatibility: for filters that accept cylindrical ceramic/quartz bio-media
How to use
Rinse the cylinders briefly with dechlorinated water to remove dust or loose particles before placement. Arrange the AquaNatura Quartz Bacteria House S cylinders in the designated biological chamber of the filter, ensuring even distribution to allow unobstructed water flow through and around the media. For new setups, seed the media with established filter material or bacteria starter to accelerate colonization. Monitor ammonia and nitrite levels regularly until stable biological filtration is established.
Usage recommendations
For best results, combine these quartz cylinders with mechanical pre-filtration to prevent clogging of pores and maintain consistent water flow. Replace or clean other filter components as needed, but avoid aggressive cleaning of the bacterial media; gentle rinsing in aquarium water is sufficient to preserve beneficial colonies.
