## Summary description

AquaNatura Quartz Bacteria Ball is a granular filter media composed of quartz beads sized 18×20 mm supplied in a 20 kg bag. Designed for aquarium and pond biological filtration, it provides surface area for beneficial bacteria colonization, improves water clarity and supports nitrogen cycle processing. Suitable for mechanical-biological filter chambers and media reactors.

## Long description

AquaNatura Quartz Bacteria Ball 18×20 mm is a granular filter media consisting of uniform quartz beads supplied in a 20 kg bag. Engineered for biological filtration in aquariums and garden ponds, the beads offer substantial surface area to promote colonization by nitrifying bacteria, contributing to nitrogen cycle stability, reduced ammonia and nitrite levels, and improved water clarity. The medium is inert, chemically stable, and suitable for use in mechanical-biological filter chambers and media reactors where durable, high-surface-area packing is required.
Advantages
The quartz bead structure provides a consistently high specific surface area for bacterial biofilm development while resisting compression and settling. Its inert mineral composition does not leach nutrients or alter water chemistry, ensuring predictable filtration performance. The uniform 18×20 mm bead size enables even water flow and low hydraulic resistance in reactors and media chambers, and the 20 kg packaging allows for bulk use in larger systems or for re-filling existing filter housings.
Suitable for
Biological filtration in freshwater and saltwater aquariums
Filtration media reactors and fluidized bed reactors
Garden pond biological filters and trickle filters
Mechanical-biological multi-chamber filtration systems
Key specifications
Material: natural quartz beads (inert mineral composition)
Bead size: approximately 18×20 mm
Form: granular/ball-shaped media for packing or reactor use
Bag weight: 20 kg
Intended use: biological filtration to support nitrifying bacteria
How to use
Rinse the media briefly with clean water before first use to remove dust from transport. Place the beads in the designated filter chamber or media reactor following the manufacturer’s guidance for media volume and flow direction. Ensure even distribution to maintain good water contact and avoid channeling. For fluidized or moving-bed reactors, adjust flow rates to keep beads in gentle motion without excessive abrasion. Monitor water parameters regularly after installation to confirm biological colonization and filtration effectiveness.
Usage recommendations
Allow a colonization period for nitrifying bacteria to establish; initial biological activity may take several days to weeks depending on stocking and organic load. Avoid cleaning the media with chlorinated tap water; use dechlorinated water or aquarium/pond water to preserve beneficial bacteria. Replace only a portion of the media at a time if long-term maintenance or replacement is needed to retain established biofilm and reduce disruption to the nitrogen cycle.
