## Long description

AquaNatura bio ball filter media with sponge and mesh, 26 mm diameter, pack of 50 is designed to support biological filtration in freshwater and marine aquariums. Each bio ball combines a structured plastic sphere that increases surface area for colonization by beneficial nitrifying bacteria with an integrated sponge layer and fine protective mesh that provide mechanical pre-filtration. The compact 26 mm size and standardized shape make these media suitable for placement in internal and external filter chambers, sumps, and custom DIY filter modules to help stabilise water quality and support the nitrogen cycle.
Advantages
These bio balls deliver a balance of biological and mechanical filtration in a single unit: the textured plastic body offers high surface area for bacterial growth while the sponge and mesh trap larger particles before they reach the biological surface. The protective mesh limits clogging and simplifies maintenance by keeping the sponge layer intact during handling. The uniform size and neutral plastic material are resistant to aquarium water conditions and will not affect water chemistry when used as directed.
Suitable for
 Freshwater and marine aquarium filter chambers
 Internal and external canister filters with media compartments
 Sumps, refugiums and DIY filtration systems
 Pre-filtration stages to protect biological media
Key specifications
 Diameter: 26 mm
 Material: durable neutral plastic body with integrated foam sponge and protective mesh
 Pack quantity: 50 pieces per pack
 Function: biological surface area with mechanical pre-filtration
 Compatibility: suitable for use in freshwater and marine aquarium filtration systems
How to use
Place the AquaNatura bio balls in a filter chamber, media basket or sump compartment where water flow will pass through them. Ensure an even distribution so that water contacts the bio ball surfaces and passes through the sponge and mesh for pre-filtration. Rinse the media briefly in dechlorinated water before first use to remove any packaging dust. Periodically inspect the sponge layer and gently rinse in aquarium water as needed to remove trapped debris without removing beneficial bacteria. Replace individual units only when damaged or when the sponge has deteriorated.
Usage recommendations
For effective biological filtration, combine these bio balls with other media types (such as ceramic rings or porous media) to create a multi-stage filtration layout. Maintain moderate, consistent flow through the media and perform regular, partial maintenance using tank water to preserve bacterial colonies while removing accumulated solids.
