## Long description

Replacement filter media bags designed for Fluval FX series canister filters, compatible with model FV-3701. Each pack contains two fine-mesh bags intended to hold loose filter media such as activated carbon, bio-media, ceramic rings or filter floss. The fine mesh keeps granular and fibrous media contained while allowing water to pass freely, helping maintain efficient mechanical and chemical filtration within the canister.
Advantages
Fine-mesh construction prevents media escape and reduces clouding caused by loose granules or fibers. Two bags per pack make it easy to prepare separate media loads or replace used bags without interrupting the entire filtration system. The bags are lightweight and flexible, conforming to the media chamber to promote even flow distribution and consistent contact between water and media.
Suitable for
Holding activated carbon, zeolite or other chemical media
Containing bio-media such as ceramic rings or bio-balls
Keeping filter floss or polishing pads tidy and contained
Organizing multiple media types within Fluval FX canister filters
Key specifications
Material: fine synthetic mesh
Pack contents: 2 media bags
Compatibility: designed for Fluval FX series canister filters (model-specific fit)
Function: contains loose media while allowing unrestricted water flow
How to use
Open a bag and place the chosen filter media inside without overpacking to ensure proper water circulation. Close the bag securely and position it in the appropriate media chamber of the Fluval FX canister following the filter manufacturer’s layout. Replace or refill the bags during regular maintenance intervals; rinse reusable media as recommended and replace disposable media according to its service life.
Usage recommendations
Use separate bags for chemical and biological media to avoid cross-contamination. Do not overfill bags; allow some internal space to maintain effective flow through the media. Inspect bags periodically for wear or damage and replace them if the mesh becomes compromised.
