Product Information
Full details
The JBL CombiBloc II Replacement Foam pack is designed for aquarium hobbyists using the JBL CristalProfi e external filter range, providing a reliable way to maintain peak filtration performance by trapping both large and small debris. These high-quality, laser-cut sponges effectively protect your biological filter media from clogging, ensuring cleaner water and improved pump longevity; however, they must be replaced periodically to prevent a decrease in filter flow rate as they accumulate organic waste.

FAQs
Are these sponges safe for reef aquariums?
Yes, the materials are inert and pollutant-free, making them safe for both freshwater and saltwater (reef) systems.
How often should I replace these?
Replacement frequency depends on your bioload. Monitor your flow rate; if rinsing no longer restores performance, it is time for a new set.
Can I use these with non-JBL filters?
These are specifically laser-cut for the JBL CristalProfi e series and may not provide a proper seal in other brands.
Should I wash these with tap water?
It is recommended to rinse them in aquarium water to avoid killing beneficial bacteria, though tap water can be used if they are being fully replaced.
What is included in the pack?
Each set includes two coarse pre-filter sponges and one fine filter sponge.
Troubleshooting
Reduced water flow from filter outlet
The pre-filter sponges are likely saturated with debris. Rinse or replace the sponges to restore flow.
Sponges are not fitting snugly
Ensure all debris has been cleared from the basket edges and that you are using the correct sponge orientation for your specific filter model.
Pros and Cons
Pros
- Perfect fit prevents water from bypassing the media
- Safe for use in both freshwater and saltwater tanks
- Protects expensive biological media from heavy fouling
- Materials are guaranteed to be inert and pollutant-free
Cons
- Requires regular replacement to maintain flow rate
- Specific to JBL CristalProfi e models only
- Not intended for permanent use without periodic cleaning
Setup, Compatibility & Care
To install, simply power off your external filter and close the shut-off valves to prevent leaks. Open the top cover of your CristalProfi e filter to access the upper basket. Remove the used sponges, clean any residual debris from the basket housing, and insert the new CombiBloc II foam set.
Compatibility includes models 402, 702, 902, 1502, and 1902. When cleaning, avoid using tap water if possible; instead, rinse the sponges in a bucket filled with existing aquarium water to preserve the beneficial bacteria colonizing the foam. If the foam begins to lose its shape or becomes too compacted to clean, replace the set entirely.
