Filter Media Net for Aquarium Filter 20 x 30 cm, ZOLUX (334020)

The Filter Media Net for Aquarium Filter 20 x 30 cm by ZOLUX is a replacement net designed to hold and organize filtration media inside canister and internal aquarium filters. Sized to 20 x 30 cm, the net provides a stable compartment for mechanical or biological media, allowing water to flow through while keeping granules, pads and loose materials in place. It is intended for routine maintenance tasks such as media replacement, cleaning and reconfiguration of filter stages in home aquariums.

Advantages

The net is made to provide reliable containment of various filter media without significantly impeding water flow. Its open-weave construction balances retention and permeability so that mechanical debris is trapped while biological media remain accessible to water and oxygen. The flexible material adapts to different filter baskets and compartments and can be cut or folded for custom arrangements. The neutral design does not react with aquarium water when used as intended.

Suitable for

• Holding loose granulated media such as activated carbon, zeolite or ceramic rings
• Organizing filter pads and floss in canister or internal filters
• Separating mechanical and biological filtration stages
• Routine filter maintenance and media replacement in home aquariums

Key specifications

• Dimensions: 20 x 30 cm
• Material: open-weave filtration net (flexible polymer fabric)
• Compatibility: suitable for canister and internal aquarium filters where size permits
• Function: contains loose media while allowing water flow through the mesh
• Reusable: can be cleaned and reused during media replacement cycles

How to use

Measure the filter compartment and place the net so it fits comfortably without obstructing inlet or outlet passages. Fill the net with the chosen filter media — for example, carbon granules, ceramic rings or filter floss — then close or fold the net opening to prevent spillage. Insert the filled net into the appropriate filter chamber, ensuring it sits securely and does not block water circulation. For maintenance, remove the net, empty or replace media as required, rinse the net in aquarium-safe water if needed, and reassemble.

Usage recommendations

Rinse the net in dechlorinated water before first use. Avoid using detergents or chemicals when cleaning; perform routine inspections to ensure the mesh remains intact and replace the net if it becomes torn or severely worn. When arranging multiple nets or media layers, maintain a clear flow path through the filter to preserve filtration efficiency.
