## Summary description

AquaNatura bio ball filter media with integrated sponge, designed for biological and mechanical filtration in aquariums. Made of PVC and PU materials, the unit has a diameter of 36 mm and combines porous bio-surface for beneficial bacteria colonization with a sponge layer for particle capture. Suitable for internal and external filter cartridges or custom filtration setups.

## Long description

AquaNatura bio ball filter media with integrated sponge, diameter 36 mm, is designed to provide combined biological and mechanical filtration in aquarium systems. The unit pairs a porous spherical surface for colonization by nitrifying and other beneficial bacteria with a foam layer that traps suspended particles. Constructed from PVC and PU materials, this filter media fits into internal and external cartridges or custom filter setups where compact, dual-function media are required.
Advantages
The compact 36 mm diameter bio ball offers a high surface-area-to-volume ratio for bacterial colonization while the integrated sponge captures fine debris and prevents clogging deeper in the filter. PVC provides structural stability and chemical resistance, while the PU sponge adds elasticity and particle retention. The combined design reduces the need for separate mechanical and biological media, simplifies maintenance, and is suitable for varied aquarium configurations.
Suitable for
 Freshwater and community aquariums requiring biological filtration support
 Internal and external filter cartridges that accept spherical media
 DIY and custom filtration systems for small to medium tanks
 Refugiums and circulation chambers where compact media are preferred
Key specifications
 Overall shape: spherical (bio ball) with integrated sponge layer
 Diameter: 36 mm
 Materials: polyvinyl chloride (PVC) and polyurethane (PU) sponge
 Function: combined biological and mechanical filtration
 Surface: porous structure suitable for beneficial bacteria colonization
 Compatibility: designed for use in cartridges, trays, or custom media chambers
How to use
Rinse the bio ball in dechlorinated water before first use to remove any production residues or loose particles. Place the unit inside a filter cartridge, media basket or custom chamber ensuring adequate water flow across the porous surface and sponge layer. Maintain regular inspection intervals and gently rinse the sponge portion in aquarium water when it becomes visibly clogged; avoid harsh squeezing or using tap water with chlorine that can reduce bacterial populations. Replace only if structural damage or irreversible clogging occurs.
Usage recommendations
For stable biological filtration, use these bio balls as part of a layered media approach: position them after coarse mechanical media and before fine polishing media to maximize lifespan and efficiency. Monitor flow rates and clean the sponge periodically to prevent channeling and maintain effective bacterial colonization.
