Media filter balls AquaNatura Raw Ore Ball Cluster 25×25 mm 0.5 kg

AquaNatura Raw Ore Ball Cluster 25×25 mm 0.5 kg are spherical media filter balls designed for aquarium and pond filtration. Supplied as 0.5 kg of uniform 25×25 mm spheres, this filter media combines mechanical particle capture with a porous surface that supports the colonization of nitrifying and heterotrophic bacteria. The media is suitable for use in internal and external filters, sumps and dedicated biofilters to help maintain water clarity and support stable biological filtration processes.

Advantages

The spherical shape and consistent size provide even flow distribution and reduce channeling inside filter chambers. The rough, porous surface offers extensive surface area for beneficial bacteria to establish, improving ammonia and nitrite conversion. As a combination mechanical and biological medium, these balls capture suspended particles while promoting long-term biofilm development, which can enhance overall filter efficiency without requiring frequent replacement.

Suitable for

• Freshwater and pond mechanical filtration
• Biological filtration in sumps and canister filters
• Pre-filtration and polishing stages in multi-media filter setups
• Filter media replacement or augmentation in existing biofilters

Key specifications

• Form: spherical media balls
• Size per sphere: approximately 25 × 25 mm
• Package weight: 0.5 kg of media
• Function: combined mechanical particle capture and biological surface support
• Compatibility: suitable for internal/external filters, sumps and biofilters

How to use

Rinse the media briefly with dechlorinated or aged aquarium/pond water before placing it in the filter to remove dust or loose fines. Position the balls in a filter chamber or media bag where water flow is steady but not turbulent, allowing contact time with passing water for mechanical trapping and biofilm development. Integrate them into the desired stage of a multi-media arrangement—typically after coarse mechanical pads and before fine polishing media—to balance particle removal and biological conversion. Monitor water parameters after installation to confirm effective biological activity and adjust media volume or placement if necessary.

Usage recommendations

Perform periodic visual inspection and gentle rinsing in aquarium or pond water when accumulated debris reduces flow; avoid using tap water with chlorine for cleaning. Replace media only when structural deterioration is evident or when biological performance cannot be restored by cleaning, and maintain complementary mechanical filtration to extend the service life of the media balls.
