## Summary description

AquaNatura Hollow Ball filter media, 500 g (0.5 kg), designed for aquarium filtration systems. Hollow spherical media provide surface area for beneficial bacteria and can be used as biological or chemical support in canister and internal filters. Suitable for freshwater and saltwater setups where compact, porous media is needed to improve water quality and support nitrogen cycle.

## Long description

AquaNatura Hollow Ball filter media, 500 g, is a compact porous spherical media designed for use in aquarium filtration systems. The hollow balls provide a large surface area within a small volume, supporting colonization by nitrifying bacteria and contributing to mechanical trapping of fine particles. Intended for both freshwater and marine tanks, this media can act as biological support or as a carrier for chemical additives when required, and it fits canister, internal and other chamber-style filters where space-efficient media is needed.
Advantages
The hollow spherical structure maximizes available surface area for beneficial bacteria while maintaining good water flow through the media. Its lightweight form allows for easy placement and removal, and the porous material promotes stable biological filtration without significantly increasing filter resistance. The neutral composition is compatible with common aquarium setups and does not release harmful substances into the water.
Suitable for
 Freshwater aquariums requiring biological filtration and surface area for beneficial bacteria
 Saltwater and reef aquaria as a compact biological/chemical media option
 Canister filters, internal filters and custom filtration chambers with limited space
 Systems where a lightweight, porous carrier for chemical resins or media additives is desired
Key specifications
 Net weight: 500 g (0.5 kg)
 Form factor: hollow spherical pellets
 Function: biological support and carrier for chemical media
 Material characteristics: porous, lightweight, water-permeable
 Compatibility: suitable for freshwater and marine aquaria
How to use
Rinse the media briefly in aquarium water before use to remove any dust. Place the hollow balls in the filter media basket or chamber according to the filter manufacturer’s guidance, ensuring consistent water flow through the media bed. For biological filtration, distribute evenly to maximize contact with water; for chemical use, combine with appropriate resins or additives as recommended by the chemical media manufacturer. Replace or rinse periodically during filter maintenance to prevent excessive clogging while preserving established bacterial colonies when possible.
Usage recommendations
Use the media as part of a multi-stage filtration approach: mechanical pre-filtration to remove solids, biological media like AquaNatura Hollow Ball for nitrification, and chemical media if specific water parameters require adjustment. Monitor water parameters (ammonia, nitrite, nitrate) after installation and during routine maintenance to assess biological activity and determine optimal cleaning intervals.
