Setup and Installation
The Eheim Filter Media Set is designed for easy integration into your compatible Eheim external filter. Always refer to your specific Eheim external filter's instruction manual for detailed steps on opening, disassembling, and reassembling the filter canister.
- Preparation: Before handling filter media, ensure your filter is disconnected from power and all hoses are properly clamped to prevent water leakage.
- Access Filter Baskets: Carefully open your Eheim external filter according to its specific instructions to access the internal filter media baskets.
- Remove Old Media: Remove the used pre-filter pad and filter fleeces from their respective positions within the filter baskets. Dispose of old media responsibly.
- Install New Media: Place the new pre-filter pad and filter fleeces into the designated compartments. The blue pre-filter pad typically goes at the top, followed by the white filter fleeces. Ensure they fit snugly without being compressed excessively.
- Reassemble Filter: Carefully reassemble your filter, ensuring all seals are correctly seated and the head is securely fastened. Reconnect hoses and restart the filter as per your filter's manual.

Operating Instructions
Once installed, the Eheim Filter Media Set operates passively within your external filter. The pre-filter pad provides mechanical filtration by capturing larger debris, while the filter fleeces offer finer mechanical filtration and a surface for beneficial bacteria to colonize, contributing to biological filtration. Ensure your filter is running continuously for optimal water quality.
Maintenance
Regular maintenance of your filter media is essential for maintaining a healthy aquarium environment and ensuring the longevity of your filter. The frequency of cleaning and replacement depends on your aquarium's bioload and the specific filter model.
- Cleaning: The filter pads and fleeces can be cleaned by gently rinsing and squeezing them out in old aquarium water (not tap water, as chlorine can kill beneficial bacteria). This removes trapped debris without completely eliminating beneficial bacteria.
- Replacement: Over time, filter media will degrade and become less effective. Replace the pre-filter pad and filter fleeces as recommended by your Eheim external filter's manual, or when they appear heavily soiled and cleaning no longer restores their effectiveness.
Troubleshooting
If you notice a decrease in your filter's performance, such as reduced water flow or cloudy water, the filter media may be clogged or require replacement.
- Reduced Flow: Check the pre-filter pad first, as it is designed to capture larger particles and can become clogged more quickly. Clean or replace as necessary.
- Cloudy Water: If water remains cloudy after cleaning the pre-filter, the finer filter fleeces may be saturated. Consider cleaning or replacing them.
- General Performance: Always ensure all filter components are correctly assembled and seals are intact after maintenance. Refer to your main filter manual for comprehensive troubleshooting steps related to the filter unit itself.
