## Summary description

Replacement filtration media pack for Fluval U4 aquarium filter by Hagen, containing activated carbon and filter floss (wadding). Designed to remove odors, discoloration and fine particles from aquarium water and to provide mechanical and chemical filtration. Suitable for routine maintenance and media replacement in Fluval U4 canister or power filters to help maintain water clarity and quality.

## Long description

Hagen Filtration Media Pack for Fluval U4 – Activated Carbon and Filter Floss is a replacement media kit designed to fit Fluval U4 canister and compatible power filters. The pack contains activated carbon and filter floss (wadding) formulated to work together to remove dissolved organic compounds, discoloration and odors while providing mechanical capture of fine particles. This media pack is intended for routine maintenance and media replacement to help restore and maintain water clarity in freshwater and most planted aquarium setups.
Advantages
The activated carbon component adsorbs dissolved impurities that cause yellowing and unwanted odors, improving water appearance without affecting biological filtration. The filter floss provides a fine mechanical barrier that traps debris and suspended particles, preventing them from recirculating. Together, these media make media replacement quick and straightforward and are shaped to integrate into the Fluval U4 media baskets for consistent flow and filtration performance.
Suitable for
Routine media replacement in Fluval U4 canister or compatible power filters
Removing discoloration and mild organic staining from aquarium water
Reducing odors and dissolved organics after medication or water changes
Mechanical removal of fine debris and suspended particulates
Key specifications
Media types: activated carbon and filter floss (wadding)
Function: chemical adsorption and fine mechanical filtration
Compatibility: designed for Fluval U4 filter models and compatible media baskets
Intended use: routine media replacement and maintenance for freshwater aquaria
How to use
Turn off and unplug the filter before opening the unit. Remove the existing media from the Fluval U4 media baskets, rinse the new filter floss briefly with dechlorinated water if recommended by the manufacturer to remove dust, and place the floss into the designated media tray. Add the activated carbon in its compartment or media bag as specified for your filter model. Reassemble the media baskets and restart the filter, checking for proper flow and seals. Replace the activated carbon regularly according to aquarium conditions and manufacturer guidance to maintain adsorption efficiency.
Usage recommendations
Do not use activated carbon continuously if you rely on long-term medication or liquid additives that should remain in the water; remove carbon during treatments to avoid removing active ingredients. Replace filter floss when visibly clogged or during scheduled maintenance cycles to preserve flow and filtration efficiency.
