## Summary description

AquaNatura Quartz Hollow Ball is a 20 kg pack of filter media consisting of hollow spherical quartz particles sized 12–14 mm. Designed for use in aquarium and pond filtration systems, these media provide mechanical filtration surface area for beneficial bacteria colonization and improved water circulation. Suitable for biological and mechanical filtration stages in canister, sump, or trickle filters.

## Long description

AquaNatura Quartz Hollow Ball 12–14 mm is a 20 kg pack of spherical quartz filter media designed for aquarium and pond filtration systems. Each hollow ball has a smooth exterior and a uniform diameter of 12–14 mm, providing stable mechanical filtration while allowing water to pass through the core. The media are suitable for use in biological stages where beneficial bacteria colonize surfaces, and in mechanical stages to trap particulates and improve flow distribution in canister, sump, or trickle filters.
Advantages
The hollow quartz balls combine a consistent particle size with a durable mineral composition that resists breakdown and abrasion. Their hollow structure increases the available surface area for biofilm development compared with solid spheres of the same size, while maintaining open channels for water circulation. Packed in a 20 kg bag, the media offer a high-volume option for larger filter chambers or for topping up existing media beds without frequent replacement.
Suitable for
Biological filtration in freshwater and saltwater aquaria
Pond filtration systems requiring stable mechanical media
Canister filters, sump filters, and trickle/biological towers
Filters where even flow distribution and surface area for nitrifying bacteria are needed
Key specifications
Form: hollow spherical quartz particles
Particle size: 12–14 mm diameter
Pack weight: 20 kg
Material: natural quartz mineral
Intended use: mechanical and biological filtration
Physical properties: hard, abrasion-resistant, chemically inert in typical aquarium conditions
How to use
Rinse the quartz hollow balls thoroughly with fresh water before first use until the runoff is clear to remove dust and fines from production and transport. Place the media in the designated compartment of a canister, sump, or trickle filter so that water flows through the bed uniformly; avoid packing the balls so tightly that flow is impeded. For biological establishment, introduce the media into a running system and allow several weeks for nitrifying bacteria to colonize the surfaces, monitoring water parameters during the initial period.
Usage recommendations
Replace or top up media incrementally rather than all at once to preserve biological stability. Periodically inspect for accumulation of detritus and perform gentle rinsing in dechlorinated water if mechanical clogging reduces flow; avoid aggressive cleaning that would remove established beneficial bacteria.
