## Summary description

AquaNatura 3DM Mineral Ring is a red filtration media for aquariums supplied in a 0.5 kg pack.

Suitable for use in canister and internal filters to improve water clarity, support nitrification, and maintain aquarium water quality for freshwater and marine systems.

## Long description

AquaNatura filtration media 3DM Mineral Ring red 20×19 mm 0.5 kg is a ceramic ring media designed for mechanical and biological filtration in home aquariums. The red rings provide a porous surface that promotes colonization by beneficial nitrifying bacteria, increasing the effective filtration area inside canister and internal filters. Supplied as a 0.5 kg package, the rings measure approximately 20×19 mm and are suitable for both freshwater and marine aquaria where stable water quality and reduced cloudiness are required.
Advantages
The mineral ring geometry offers a high surface-to-volume ratio that supports a broad population of nitrifying bacteria while also trapping particulate matter for improved mechanical filtration. The ceramic composition is chemically stable and does not alter water parameters, making it suitable for sensitive freshwater and marine environments. Compact ring size ensures good water flow and even distribution inside filter chambers, helping to maintain consistent biological activity and clearer water.
Suitable for
Canister filters for freshwater and marine aquariums
Internal and hang-on-back filters requiring biological media
Systems aiming to improve nitrification and reduce ammonia/nitrite levels
Community tanks where stable water clarity and quality are needed
Key specifications
Material: porous ceramic mineral media
Shape and size: ring, approximately 20×19 mm
Pack weight: 0.5 kg
Function: mechanical and biological filtration support
Compatibility: suitable for freshwater and marine aquarium systems
How to use
Rinse the mineral rings thoroughly in dechlorinated water or aquarium water before first use to remove dust and loose particles. Place the rings in the filter media tray or basket, ensuring an even layer that allows unrestricted water flow through the rings. For canister filters, position the rings in the biological media section; for internal filters, use available media compartments or an external media bag if required. Replace a portion of the rings gradually during media maintenance to preserve the established bacterial colony and avoid sudden declines in biological filtration capacity.
Usage recommendations
For best results, use the AquaNatura mineral rings in combination with mechanical pre-filtration to reduce clogging. Monitor ammonia and nitrite levels after installation and during routine maintenance; avoid cleaning all rings at once to preserve beneficial bacteria. If used in marine systems, rinse in saltwater from the aquarium to retain the native microbial community.
