## Long description

Hagen ClearMax filter cartridge designed for Fluval U4 offers a direct-fit replacement media for routine maintenance of compatible aquarium canister filters. Model 010578 provides the appropriate form factor and media layers required for the mechanical and chemical stages in the Fluval U4 system, supporting removal of debris and soluble contaminants to help maintain water clarity and a stable aquatic environment.
Advantages
The Hagen ClearMax replacement cartridge integrates mechanical and chemical filtration in a single, pre-assembled unit to simplify cartridge swaps and reduce downtime. Its layered media capture particulate matter while activated carbon or other chemical media adsorb odors and dissolved organics. The cartridge is shaped to fit the Fluval U4 filter chamber securely, ensuring even water flow through the media and predictable filtration performance.
Suitable for
 Routine cartridge replacement in Fluval U4 aquarium filters
 Maintaining water clarity in freshwater and planted aquariums
 Reducing suspended debris and adsorbing dissolved organic compounds
 Quick media swaps during scheduled maintenance
Key specifications
 Form factor: pre-assembled cartridge compatible with Fluval U4 filter chamber
 Filtration types: combined mechanical and chemical media layers
 Mechanical media: fine fibers or foam layer for particulate capture
 Chemical media: activated carbon or equivalent adsorbent layer for dissolved contaminants
 Use interval: intended for routine replacement as part of regular maintenance (replace frequency depends on aquarium bioload and water parameters)
How to use
Shut off and disconnect the Fluval U4 filter according to the manufacturer’s instructions, then open the filter housing and remove the used cartridge. Insert the Hagen ClearMax cartridge into the correct chamber with the media oriented as shown in the Fluval U4 manual, close the housing and restart the filter. Monitor flow and water clarity after installation and follow the Fluval U4 maintenance schedule for cartridge replacement intervals.
Usage recommendations
Replace the cartridge at intervals appropriate to tank size and stock density; inspect for reduced flow or discoloration of the media and change sooner if necessary. When changing cartridges, avoid replacing all biological media at once to preserve beneficial bacteria—if biological filtration is present elsewhere in the system, stagger replacements. Rinse hands and the new cartridge in aquarium water if recommended by the filter manual, and always follow Fluval U4 safety and installation guidelines.
