## Summary description

Quartz Bacteria Ball filter media by AquaNatura, packed 0.5 kg of 18×20 mm spherical quartz media designed for biological filtration in aquariums and ponds. Provides high surface area for colonization of beneficial bacteria, supports nitrification, and improves water quality when placed in filter housings, canisters or wet/dry systems.

## Long description

AquaNatura Quartz Bacteria Ball filter media 18×20 mm 0.5 kg is spherical quartz media designed for biological filtration in aquariums and garden ponds. Each 18×20 mm bead provides a hard, inert surface that promotes colonization of nitrifying bacteria. Supplied as a 0.5 kg pack, the media is suitable for placement in filter housings, canister filters, and wet/dry systems where a dense population of beneficial bacteria is required to support the nitrification process and maintain water quality.
Advantages
The spherical quartz construction offers high mechanical strength and chemical inertness, which prevents breakdown and release of contaminants into the water. The smooth but durable surface encourages rapid bacterial biofilm formation while resisting compaction, allowing even water flow and efficient gas exchange. Because the media is mineral-based, it does not alter water chemistry and is suitable for long-term biological use. The uniform bead size ensures consistent packing and predictable hydraulic behaviour in a variety of filter types.
Suitable for
 Biological filtration in freshwater aquariums
 Biological filtration in garden ponds
 Placement inside canister and box filters
 Use in wet/dry and trickle filter systems
Key specifications
 Material: natural quartz (spherical beads)
 Bead size: approximately 18 × 20 mm
 Pack weight: 0.5 kg
 Shape: spherical for uniform packing and flow
 Chemical properties: inert, non-reactive in aquarium water
How to use
Rinse the required amount of quartz bacteria balls under tap water until runoff is clear to remove dust from packaging. Place the media inside the filter chamber or canister so that water flows evenly through the bed of beads; avoid packing so tightly that water flow is restricted. For wet/dry systems, position the beads where maximum air–water contact occurs to support aerobic bacterial activity. Monitor biological performance via ammonia and nitrite tests and adjust media volume if necessary to meet the bio-load of your aquarium or pond.
Usage recommendations
For initial colonization, consider adding seeded media from an established filter to accelerate bacterial growth. Clean the media gently by rinsing in aquarium water during maintenance to preserve beneficial bacteria. Replace only when beads are physically damaged or when filter performance cannot be restored by cleaning.
