1. Introduction
This manual provides instructions for the installation, operation, and maintenance of the OASE Filtoclear 4000 Foam Filter Set. This set contains replacement filter media designed for OASE FiltoClear Pressure Filters, ensuring effective mechanical filtration for clear pond water.
2. Product Overview

Figure 1: OASE Filtoclear 4000 Foam Filter Set. This image shows the filter unit with its top lid removed, revealing layers of blue and orange filter foams stacked inside the black cylindrical housing. A handle is visible on the top lid, along with inlet and outlet connections.
The OASE Filtoclear Foam Filter Set consists of high-quality replacement filter foams. These foams are crucial for the mechanical filtration process within your OASE FiltoClear Pressure Filter, effectively removing debris and particulate matter from pond water.
The set includes a specific number of blue and red (orange) foams tailored to different FiltoClear filter models. For the Filtoclear 4000, the exact foam configuration should be verified against your existing filter's requirements or the product packaging.
3. Installation and Setup
Before beginning installation, ensure your OASE FiltoClear Pressure Filter is disconnected from power and water supply. Refer to your main FiltoClear filter manual for specific safety instructions.
- Access Filter Housing: Carefully open the main FiltoClear filter housing according to its specific instructions. This usually involves releasing clamps or unscrewing a lid.
- Remove Old Foams: Extract the used or worn-out filter foams from the filter unit. Dispose of old foams responsibly.
- Insert New Foams: Place the new OASE Filtoclear Foam Filter Set into the filter housing. Ensure the foams are correctly oriented and stacked as per the original configuration or the guide below. The super porous material should be evenly distributed to maximize filtration efficiency.
- Secure Housing: Close and secure the filter housing, ensuring all seals are properly seated to prevent leaks.
- Reconnect: Reconnect the filter to the water supply and power.

| NEW Oase FiltoClear 16000 Filter | 4 | 3 |
| NEW Oase FiltoClear 20000/30000 Filter | 5 | 4 |
4. Operation
Once the new foam filter set is installed and the main FiltoClear unit is reconnected and powered, the filter will resume its normal operation. The foams provide mechanical filtration by trapping suspended particles and debris as water passes through them. This process contributes to maintaining clear and healthy pond water.
The different densities or types of foams (blue and red/orange) are designed to capture various sizes of particles, optimizing the filtration process.
5. Maintenance
Regular maintenance of the filter foams is essential for optimal performance of your OASE FiltoClear Pressure Filter. The frequency of cleaning or replacement depends on the pond's bio-load and water conditions.
- Routine Cleaning: Periodically, the foams will become saturated with debris. Refer to your main FiltoClear filter manual for instructions on how to perform routine cleaning of the foams, which often involves a cleaning mechanism within the filter itself.
- Replacement: Over time, filter foams degrade and lose their effectiveness. Replace the foam filter set when you observe a decrease in filtration efficiency, or when the foams show signs of significant wear or damage. The OASE Filtoclear Foam Filter Set is designed for easy replacement.
- Disposal: Dispose of old filter foams according to local environmental regulations.
6. Troubleshooting
If you experience issues with your pond filtration after installing the new foam set, consider the following:
- Unclear Water:
- Ensure the new foams are correctly installed and seated within the filter housing.
- Check if the filter housing is properly sealed to prevent bypass.
- Verify that the main filter unit's UV-C clarifier (if applicable) is functioning.
- Consider if the foams are already saturated and require cleaning or earlier replacement due to heavy pond debris.
- Reduced Water Flow:
- The foams might be clogged. Perform a routine cleaning cycle.
- Check for blockages in the inlet or outlet pipes of the main filter unit.
- Leaks:
- Ensure the filter housing lid is securely fastened and the O-ring seal is clean and properly seated.
For persistent issues, consult the complete OASE FiltoClear Pressure Filter manual or contact OASE customer support.
