## Summary description

AquaNatura raw ore ball cluster for filtration media, supplied as 25×25 mm spherical pieces in a 20 kg pack. Designed for use in aquarium and pond filter systems as mechanical and/or biological media, these mineral filter balls provide surface area for beneficial bacteria and help trap particulate matter. Suitable for large-scale filtration setups and media-filled filter chambers.

## Long description

AquaNatura raw ore ball cluster 25×25 mm media filter balls come as uniform spherical pieces with a nominal diameter of 25×25 mm and are supplied in a 20 kg pack. These mineral filter balls are intended for use in aquarium and pond filter systems where they function as mechanical and biological media. The porous surface and consistent size make them suitable for installation in media-filled chambers, biofilters and large-scale filtration setups where stable hydraulic properties and surface area for microbial colonization are required.
Advantages
The mineral composition and spherical shape provide a stable, low-turbulence packing that promotes even flow distribution and reduces channeling. Their surface texture supports colonization by beneficial bacteria to assist biological filtration while also trapping suspended particulate matter for mechanical filtration. Supplied in a 20 kg pack, the media is convenient for filling large filter housings or topping up existing media beds without frequent replenishment.
Suitable for
Aquarium internal and external filter chambers
Pond filter systems and biofilters
Large-scale filtration setups and media beds
Mechanical pre-filtration combined with biological colonization
Key specifications
Shape: spherical filter balls with nominal diameter 25×25 mm
Pack size: 20 kg per pack
Material type: raw mineral/ore-based media suitable for aquatic filtration
Function: combined mechanical and biological filtration media
Surface: textured to increase surface area for bacterial colonization
How to use
Rinse the filter balls briefly with clean water to remove dust from transport before placing them into the filter chamber. Arrange the media so that water flows evenly through the bed—avoid compressing the balls tightly to maintain porosity and hydraulic flow. For biological maturation, allow several weeks of operation to permit growth of beneficial bacteria; during this period, avoid complete media replacement to preserve established colonies. Monitor flow rates and mechanical load and perform routine maintenance such as gentle rinsing in tank/pond water when particulate build-up reduces flow.
Usage recommendations
Use the AquaNatura raw ore ball cluster as part of a multi-stage filtration system combining mechanical and biological elements. For best results, pair with coarse mechanical pre-filtration and occasional backwashing or gentle rinsing; replace only a portion of the media at a time to maintain biological stability.
