4. Setup
4.1. Filter Media Installation
The filter media should be arranged in the baskets as follows, from bottom to top:
- Ceramic Rings (Tetra CR Filterrings): Place in the bottom basket. These retain larger particles and ensure homogeneous water flow.
- BioFoam (Tetra BF BioFoam): Place above the ceramic rings. This biological filter sponge retains medium-sized particles and promotes beneficial bacteria colonization.
- Activated Carbon (Tetra CF Carbon): Place above the BioFoam. The carbon granules in a mesh bag remove harmful organic substances, odors, and water discoloration.
- Filter Floss (Tetra FF FilterFloss): Place in the top basket. This fine floss retains the smallest particles not captured by other filter elements.

4.2. Hose Connection and Placement
Connect the inlet and outlet hoses to the filter unit and secure them with the provided clamps. Position the filter unit on a stable surface below the aquarium. The rotatable connection valves allow for easy hose alignment. Secure the inlet and outlet pipes inside the aquarium using the suction cups.

4.3. Priming and Startup
After connecting all hoses and placing the filter, ensure the quick-release valve is in the open position. Use the integrated suction aid to prime the filter by pressing it repeatedly until water flows into the filter unit and hoses. Once water fills the system, connect the power plug to an electrical outlet. The filter should start operating. Check for any leaks immediately.
5. Operating Instructions
Once the filter is set up and running, it will continuously filter your aquarium water. The flow rate can be adjusted using the valves on the quick-release unit. Turn the valves to increase or decrease the water flow as needed for your aquarium's specific requirements. Monitor the water clarity and fish behavior to ensure optimal filtration.
6. Maintenance
Regular maintenance is crucial for the efficient operation and longevity of your Tetra EX 500 Plus filter. Always disconnect the power supply before performing any maintenance.
6.1. Regular Cleaning
The frequency of cleaning depends on your aquarium's bioload. Generally, the pre-filter sponge should be rinsed every 1-2 weeks, and the main filter media cleaned every 4-6 weeks.
- Disconnect the power.
- Close the quick-release valves and detach the hose unit from the filter head.
- Carefully remove the filter head and then the filter media baskets.
- Rinse the mechanical filter media (filter floss, biofoam) with aquarium water to remove trapped debris. Do not use tap water as it can kill beneficial bacteria.
- Replace activated carbon every 4 weeks, as its adsorptive capacity diminishes over time.
- Reassemble the filter media baskets in the correct order.
- Reattach the filter head and hose unit, ensuring all seals are properly seated.
- Open the quick-release valves and prime the filter as described in the setup section.
- Reconnect power.
6.2. Impeller Cleaning
Periodically inspect and clean the impeller located in the filter head. Remove the impeller cover and clean the impeller and its chamber with a small brush to remove any debris or mineral buildup that could affect performance or cause noise.
7. Troubleshooting
If you encounter issues with your Tetra EX 500 Plus filter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Water Flow | Clogged filter media, dirty impeller, kinked hoses. | Clean or replace filter media. Clean impeller. Check and straighten hoses. |
| Filter Not Starting | Not plugged in, power outage, air in system, faulty impeller. | Check power connection. Prime the filter. Inspect/replace impeller. |
| Excessive Noise | Air trapped in filter, dirty/damaged impeller, filter not level. | Re-prime the filter to remove air. Clean or replace impeller. Ensure filter is on a level surface. |
| Leaking | Improperly sealed O-ring, loose hose connections, cracked housing. | Check and reseat O-rings. Tighten hose clamps. Inspect housing for damage. |
