Filter media net AquaNatura 28×32 cm black polyester for aquarium filtration

AquaNatura filter media net is a black polyester mesh sized 28×32 cm, designed to contain loose filtration media inside aquarium filters while allowing effective water flow and biological activity. The open-weave polyester fabric keeps sponges, ceramic rings, bio-balls and other granular media in place, preventing migration of particles into the filter chamber or aquarium. Its flexible, easily cut and folded sheet form makes it suitable for creating DIY media bags, replacing worn media holders in canister or internal filters, or customizing media arrangement in refugia and sump sections.

Advantages

The polyester construction provides durability and resistance to water and routine cleaning, while the black color minimizes visible staining and blends with filter interiors. The mesh size balances retention of media with unrestricted water circulation to maintain mechanical and biological filtration. The sheet is easy to trim, fold or sew to create pockets and bags, allowing precise placement of different media types and simplified maintenance.

• Holding sponges, ceramic rings, bio-balls and granular media
• DIY media bags and custom filter inserts
• Replacement of media mats or holders in canister and internal filters
• Organizing media in sumps, refugiums and breeding tanks

How to use

Measure and cut the polyester net to the required dimensions for your filter compartment. Place loose media such as ceramic rings, bio-balls or sponge pieces onto the net and fold or sew edges to form a pouch or bag if needed. Insert the assembled media bag into the filter tray, canister basket or sump chamber ensuring unobstructed water flow through the mesh. For partial replacements, trim the net to fit around existing components and secure with plastic clips or washable thread.

Usage recommendations

Rinse the net in aquarium water after initial assembly to remove manufacturing residues. During routine maintenance, inspect the mesh for clogging and gently squeeze or rinse with tank water to preserve beneficial bacteria. Replace the net if fraying or permanent deformation occurs to avoid release of small fibres into the system.
