## Summary description

MARINA Aqua Natura Bio Ball is a plastic filtration insert with a 48 mm diameter made of polypropylene (PP). Designed for biological filtration in aquarium systems, the spherical media provides surface area for beneficial bacteria colonization and improves water quality by supporting nitrification. Suitable as a replacement media in compatible aquarium filters for freshwater setups.

## Long description

MARINA Aqua Natura Bio Ball insert is a polypropylene (PP) spherical filtration media with a 48 mm diameter designed for biological filtration in freshwater aquarium systems. The open, curved surfaces of the bio ball provide extensive area for colonisation by nitrifying bacteria, helping to convert ammonia and nitrite into less harmful nitrate and contributing to clearer, more stable water conditions. The compact, replaceable shape makes it suitable as a drop-in media for compatible external and internal filters that accept modular biological cartridges or loose media.
Advantages
The MARINA Aqua Natura Bio Ball is made of durable, inert PP material that resists breakdown and does not affect water chemistry. Its spherical geometry maximises surface area relative to volume while allowing good water flow and oxygen access to bacterial colonies. Installation and replacement are straightforward due to its standard 48 mm diameter, and the media is lightweight and easy to rinse for routine maintenance.
Suitable for
Freshwater aquarium biological filtration
Replacement media in compatible internal or external filters
Modular media chambers and media baskets
Start-up and maintenance of nitrification cycles
Key specifications
Material: Polypropylene (PP)
Shape: Spherical bio ball
Diameter: 48 mm
Function: Biological filtration media for nitrifying bacteria
Suitable water type: Freshwater aquaria
How to use
Rinse the MARINA Aqua Natura Bio Ball in dechlorinated water or aquarium water to remove any packaging dust before first use. Place the bio ball in the biological media chamber, media basket, or loose media compartment of a compatible filter. Ensure water flows evenly through the media to maintain oxygenation of bacterial colonies. Do not use strong disinfectants or boiling water when cleaning; instead, perform gentle rinses in aquarium water during water changes to preserve beneficial bacteria.
Usage recommendations
For best results, combine the bio balls with mechanical filtration placed upstream to reduce solid accumulation. When starting a new tank, seed the media with established filter material or use a commercial bacterial starter to accelerate colonisation. Replace only as needed and avoid complete simultaneous replacement to maintain biological stability.
