## Summary description

sera PrefiX Filter is a replacement filtration cartridge designed for use with compatible external pumps and canister (external) aquaria filters. It provides mechanical and biological filtration support by trapping debris and offering surface area for beneficial bacteria.

## Long description

The sera PrefiX Filter cartridge is a replacement filtration element intended for use with compatible external pumps and canister (external) aquarium filters. Designed to provide mechanical particle removal and an increased surface area for beneficial bacteria, this cartridge supports routine maintenance of freshwater aquaria by helping to maintain water clarity and biological balance.
Advantages
This replacement cartridge offers combined mechanical and biological filtration in a single element, capturing suspended particles while providing porous surfaces for colonisation by nitrifying bacteria. Its shape and dimensions are suitable for insertion into compatible external pump housings and canister filter chambers, making cartridge swaps straightforward and reducing downtime during maintenance. The neutral material is suitable for typical freshwater aquarium conditions and contributes to predictable filtration performance when replaced at recommended intervals.
Suitable for
 Routine cartridge replacement in compatible external pump filters
 Use as the mechanical/biological medium in canister and external aquarium filters
 Freshwater aquaria where regular maintenance and water clarity are required
When it may not be suitable
This replacement cartridge is intended for compatible external pumps and canister filters; it may not fit proprietary or non-standard filter models. It is designed for mechanical and biological filtration and does not contain chemical media such as activated carbon or phosphate removers, so it is not a complete solution for chemical contamination or specialised treatment needs.
Key specifications
 Filtration type: mechanical and biological
 Application: external pump filters and canister (external) aquarium filters
 Suitable water type: freshwater aquaria
 Material: porous filter media suitable for bacterial colonisation
 Intended use: routine cartridge replacement for maintenance of water clarity and biofiltration
How to use
Shut down the pump or filter and follow the manufacturer’s instructions for opening the filter housing. Remove the spent cartridge and dispose of it according to local regulations. Insert the sera PrefiX replacement cartridge ensuring correct orientation and seating within the filter chamber, then reassemble the unit and restart the system. Rinse new cartridges briefly in dechlorinated water if recommended by the filter manufacturer. Replace cartridges at regular intervals based on bioload and water quality measurements.
What to consider before purchase
 Check physical compatibility with your external pump or canister filter model and available space inside the filter housing
 Confirm that a mechanical/biological cartridge meets your filtration needs; chemical issues require additional media
 Assess replacement interval based on aquarium bioload and water clarity requirements
Usage recommendations
For stable biological filtration, replace the cartridge according to manufacturer guidance and avoid replacing all biological media at once; stagger changes to preserve beneficial bacteria. Combine with appropriate chemical media if removal of dissolved organics or pollutants is required.
