## Long description

AquaNatura TN-45178 filtration media mesh bag is a white polyester pouch sized 15×30 cm with a secure zip closure. Designed for aquarium and pond filtration systems, this mesh bag contains loose filter media such as activated carbon, ceramic rings or biological media while allowing efficient water flow through the fabric. The polyester mesh balances containment and permeability so media remain in place without restricting filter performance, and the zip closure simplifies loading and replacement during routine maintenance.
Advantages
The polyester construction resists tearing and retains shape when wet, providing durable containment of granular or irregular-shaped media. Its fine open-weave allows effective water circulation for mechanical, chemical and biological filtration functions. The zip closure offers a reliable, reusable seal that reduces media loss and simplifies handling when refilling or cleaning the bag.
Suitable for
 Holding activated carbon to control odors and discoloration
 Containing ceramic rings or bio-media for biological filtration
 Keeping coarse media or fines together in canister and pond filters
 Temporary use during filter media replacement and maintenance
Key specifications
 Material: white polyester mesh
 Dimensions: 15 × 30 cm
 Closure type: zip / zipper
 Permeability: open-weave mesh allowing water flow
 Intended use: containment of loose filtration media for aquaria and ponds
How to use
Open the zip closure and fill the bag with the chosen filtration media — activated carbon, ceramic rings, bio-balls or other loose media — leaving a small free space to allow water circulation. Close the zipper fully to prevent spillage. Place the bag inside the filter chamber or canister where flow passes evenly through the mesh. For ponds, secure the bag in a media compartment or basket. Remove and replace or recharge media according to manufacturer guidance for the specific media used.
Usage recommendations
Rinse newly filled media in freshwater before placing the bag into the filter to remove dust and fines. Inspect the mesh bag periodically for wear or clogging and replace if the weave becomes damaged or flow is significantly reduced. Do not overload the bag with excessively fine powdery media that may pass through the mesh; use a secondary pre-filter or finer containment if needed.
