## Summary description

AquaNatura bio ball filter media with integrated sponge is a filtration insert for aquariums and small pond filters. Made of PVC and PU, diameter 16 mm, it provides mechanical and biological filtration by trapping debris and offering surface area for beneficial bacteria. Suitable for internal filters, canister filters or DIY filter setups to improve water clarity and biological balance.

## Long description

The AquaNatura Filter media bio ball with sponge is a compact filtration insert designed for aquariums and small pond filters. Constructed from PVC and PU with an external diameter of 16 mm, this bio ball combines mechanical and biological filtration: the integrated sponge captures suspended particles while the structured plastic body provides extensive surface area for colonisation by nitrifying bacteria. Its small, uniform shape makes it suitable for placement in internal filters, canister filters, or custom DIY filter media chambers to support clearer water and stable biological balance.
Advantages
The product offers dual-stage filtration in a single element, reducing the need for separate mechanical and biological media. Its PVC framework ensures durable structure and consistent flow-through, while the PU sponge section efficiently traps debris and is easy to rinse. The compact 16 mm diameter bio balls are simple to dose, arrange, or replace in a variety of filter housings and are chemically inert, avoiding unwanted reactions with aquarium water.
Suitable for
 Internal aquarium filters where small media size is required
 Canister filters with media baskets or trays
 DIY filter setups and small pond filtration systems
 Biological filtration support in freshwater aquaria and shrimp tanks
When it may not be suitable
These 16 mm bio balls are intended for small to medium filter chambers and may be impractical in large-volume filters that require higher individual media flow or greater void volume. They are not a complete filtration solution on their own for heavily stocked or heavily fed aquaria; in such cases larger or additional media types may be needed to manage organic load and maintain water quality.
Key specifications
 Material: PVC framework with PU sponge insert
 External diameter: 16 mm
 Filtration types: mechanical (sponge) and biological (porous plastic surface)
 Colour: neutral (typical plastic and sponge tones)
 Suitable water types: freshwater aquaria and small pond systems
How to use
Place the AquaNatura bio balls in the media basket, tray, or chamber of your filter so that water flows evenly through the sponge and plastic structure. For new installations, rinse the media briefly with dechlorinated water to remove any manufacturing residues; avoid using tap water containing chlorine that could harm beneficial bacteria. Distribute the bio balls to maintain good water circulation and replace or clean sponge elements periodically: gently squeeze the sponge in aquarium water during maintenance to remove trapped debris while preserving bacterial colonisation on the plastic surfaces.
What to consider before purchase
 Confirm that 16 mm diameter media fits the filter’s media basket or tray dimensions
 Assess aquarium stocking levels to determine the required volume of biological media
 Decide whether integrated sponge media suits your maintenance routine (requires periodic gentle cleaning)
 Ensure compatibility with freshwater systems if used in ponds or non-standard setups
Usage recommendations
For most freshwater aquaria, use these bio balls alongside coarse mechanical media and, if needed, chemical media such as activated carbon. Monitor ammonia, nitrite and nitrate levels after installation and during cycling to confirm sufficient biological activity. During routine maintenance, clean only a portion of the media at a time to preserve beneficial bacteria and avoid disrupting the biological balance.
