## Summary description

AquaNatura bio ball filter media, 36 mm diameter, designed with a central sponge core and outer mesh for mechanical and biological filtration. Supplied as a pack of 18 pieces, these bio balls provide surface area for beneficial bacteria while retaining debris in the sponge. Suitable for freshwater and marine aquarium filtration systems, media reactors, and internal filters.

## Long description

AquaNatura bio ball filter media 36 mm with sponge core and mesh, pack of 18 is a dual-function filtration element designed for aquarium use. Each bio ball combines a porous sponge center with a protective outer mesh shell to provide both mechanical debris capture and increased surface area for nitrifying bacteria. The 36 mm diameter and compact spherical shape make these media compatible with a variety of freshwater and marine internal filters, media reactors and sump chambers.
Advantages
The integrated sponge core traps suspended particles and prevents clogging of the surrounding mesh, while the outer open-weave mesh maintains good water flow and exposes a large surface suitable for biofilm formation. The 36 mm size delivers a balance between packing density and available surface area, and the pack of 18 pieces allows for configuring filter media volume according to aquarium size and flow rate. Materials used resist typical aquarium conditions and support stable biological filtration when cycled properly.
Suitable for
Freshwater aquarium internal filters
Marine aquariums and reef sumps
External media reactors and canister filter baskets
Biological filtration upgrades in small to medium tanks
Key specifications
Diameter: 36 mm (each bio ball)
Core: porous sponge for mechanical filtration
Outer layer: mesh shell to increase surface area and protect the sponge
Pack quantity: 18 pieces
Compatibility: suitable for freshwater and marine environments
How to use
Rinse the bio balls briefly with dechlorinated water before first use to remove any loose particles. Place them in the filter chamber, media reactor or canister basket so that water flows evenly through the spheres. Positioning should allow adequate circulation around each ball to ensure contact with dissolved and suspended waste, enabling mechanical trapping in the sponge and colonisation of beneficial bacteria on the mesh. Replace individual units if the sponge core becomes irreversibly compacted or damaged; otherwise maintain them as part of the overall filter maintenance routine.
Usage recommendations
For effective biological filtration, introduce the bio balls as part of a staged media arrangement: mechanical media upstream to remove large debris, then the AquaNatura bio balls for bacterial colonisation, followed by any polishing media if required. Avoid cleaning all bio balls simultaneously to preserve established bacterial colonies; rinse a portion at a time in aquarium water during regular maintenance.
