Replacement cartridge for sera Fil 60/120 aquarium filter, model SE-06850

Replacement cartridge designed for sera Fil 60/120 aquarium filters (model SE-06850). This cartridge provides combined mechanical and biological filtration media compatible with the specified filter series. It is intended for regular cartridge replacement to maintain water clarity, reduce particulate load and support colonies of beneficial bacteria in freshwater and planted aquaria as recommended by the filter manufacturer.

Advantages

The cartridge integrates layers for mechanical trapping of debris and a porous biological medium to promote nitrifying bacteria colonisation. Its dimensions and media composition are matched to sera Fil 60/120 filters to ensure a secure fit and steady flow. Using the original replacement cartridge helps maintain designed filtration performance and reduces the need for more frequent deep maintenance.

Suitable for

• sera Fil 60 aquarium filters
• sera Fil 120 aquarium filters
• Freshwater and planted aquaria requiring routine cartridge replacement
• Environments where mechanical debris removal and biological filtration support are needed

Key specifications

• Type of filtration: combined mechanical and biological media
• Compatibility: designed to fit sera Fil 60 and Fil 120 filter housings
• Form factor: replaceable cartridge sized for the specified filter models
• Media composition: layered mechanical filter material plus porous biological substrate
• Intended use: regular replacement to sustain filtration efficiency and water clarity

How to use

Switch off the filter and disconnect power before opening the filter housing. Remove the used cartridge and dispose of it according to local regulations. Insert the replacement cartridge into the filter housing in the correct orientation so that it seats securely. Reassemble the filter housing, restore power, and check for proper water flow and absence of leaks. Follow the filter manufacturer’s recommendations for replacement intervals and any priming steps required after cartridge change.

Usage recommendations

Replace the cartridge at intervals recommended by the filter manufacturer or sooner if you notice reduced flow or increased turbidity. When installing, ensure seals and O-rings on the filter are inspected and clean to avoid bypass and maintain effective mechanical and biological filtration.
