## Summary description

AquaNatura 16 mm bio balls for aquarium filtration, supplied in a pack of 100 with a sponge and a net. Designed for biological and mechanical filtration, these small plastic media increase surface area for beneficial bacteria while the included sponge captures debris. Suitable for home aquariums and external or internal filter trays where compact media are required.

## Long description

AquaNatura aquarium filter bio balls 16 mm with sponge and net, pack of 100 are compact plastic filtration media designed to support biological and mechanical filtration in home aquariums. Each spherical bio ball measures 16 mm and provides a textured surface that increases the available area for colonisation by beneficial nitrifying bacteria. The package includes a polyester sponge to trap larger particulate matter and a mesh net for easy placement and retrieval of the media from filter trays, sumps or internal filter compartments.
Advantages
The rounded shape and open structure of the 16 mm bio balls create high surface area-to-volume ratio that promotes stable biological filtration without significantly restricting water flow. Inclusion of a sponge provides immediate mechanical filtration to remove detritus and suspended solids, reducing clogging of the bio media. The supplied net simplifies maintenance by keeping the balls together for quick cleaning or replacement. The small size suits compact filter spaces while maintaining effective colonisation for nitrifying bacteria.
Suitable for
Small to medium-sized home aquariums requiring compact biological media
External or internal filter baskets and trays with limited space
Sump systems and DIY filter modules where modular media placement is needed
Temporary or emergency filtration when quick mechanical and biological support is required
Key specifications
Quantity: 100 pieces
Individual diameter: 16 mm
Material: durable aquarium-grade plastic
Includes: polyester sponge and mesh net
Function: combined mechanical and biological filtration media
How to use
Rinse the bio balls and sponge with dechlorinated water before first use to remove any packaging residue. Place the required number of bio balls into the filter compartment, basket or mesh net to suit the flow path; use the supplied net to contain the media for easy handling. Position the sponge upstream of the bio balls to capture debris and prolong biological activity. During routine maintenance, lift the net or remove the sponge and rinse gently in tank water to preserve beneficial bacteria while removing accumulated solids.
Usage recommendations
For best results, avoid cleaning the bio balls with tap water containing chlorine; use aquarium water during regular maintenance to retain beneficial bacterial colonies. Monitor flow rates—if water passes too quickly, increase the quantity of media or slow the flow to allow sufficient contact time for biological filtration. Replace the sponge periodically when it shows signs of irreversible clogging or deterioration.
