## Summary description

Tetra Bio-Balls BB 800 ml are biological filtration media designed for aquarium filters. The polymer ball elements provide a large surface area for beneficial nitrifying bacteria, improving biological filtration and water quality. Suitable for use in canister and internal filter media compartments, these bio-balls support ammonia and nitrite breakdown and help maintain stable aquarium ecosystems.

## Long description

Tetra Bio-Balls BB 800 ml are biological filtration media engineered for aquarium canister filters and internal filter compartments. Manufactured from polymer material shaped into hollow balls, these media provide a large specific surface area that promotes colonisation by nitrifying bacteria. By increasing the available surface for beneficial micro-organisms, the Bio-Balls support the breakdown of ammonia and nitrite, contributing to a more stable and healthy aquarium environment.
Advantages
The open, spherical design of these bio-balls creates extensive flow-through channels that improve contact between water and bacterial colonies while minimising clogging. Their inert polymer composition is chemically stable and does not alter water parameters. Packed in an 800 ml volume, the media deliver a high surface-to-volume ratio for effective biological filtration in canister and internal filters. The lightweight structure is easy to handle and rinse for routine maintenance.
Suitable for
 Freshwater and saltwater aquariums requiring improved biological filtration
 Canister filters and internal filter media compartments
 Systems aiming to stabilise ammonia and nitrite levels
 Aquariums with moderate to high bioload where additional bacterial surface is needed
Key specifications
 Media type: polymer bio-balls with open, hollow structure
 Volume: 800 ml
 Function: biological filtration support for nitrifying bacteria
 Compatibility: suitable for canister and internal filter media baskets
 Chemical stability: inert material that does not release additives into water
 Maintenance: washable and reusable with gentle rinsing
How to use
Rinse the Bio-Balls briefly with aquarium water to remove dust from packaging before installation. Place the media into the designated biological media compartment or media basket of your canister or internal filter, ensuring free water flow through the balls. Distribute evenly to avoid channeling and to maximise contact between water and bacterial colonies. During routine maintenance, rinse the media in dechlorinated or aquarium water to preserve beneficial bacteria and avoid vigorous scrubbing that removes established colonies.
Usage recommendations
For best results, combine the Bio-Balls with mechanical filtration ahead of the biological media to prevent rapid clogging. Monitor water parameters regularly after installation and adjust media volume based on bioload and aquarium size. Replace or supplement media gradually to avoid disturbing the biological balance.
