- Connect Power: Once the filter is securely installed and fully submerged, connect the power cable to a suitable electrical outlet.
5. Operating Instructions
The Bioplus Thermo 200 operates continuously to filter and heat your aquarium water. After initial setup, ensure the filter is running smoothly and quietly. The integrated heater will automatically maintain the set temperature. The adjustable diffuser allows you to customize surface movement, which helps prevent biofilm formation and provides additional dissolved oxygen to the water. Monitor your aquarium's water parameters regularly to ensure optimal conditions.
6. Maintenance
Regular maintenance is crucial for the longevity and efficiency of your filter and the health of your aquarium. The modular design simplifies this process.
- Disconnect Power: Always unplug the filter from the power outlet before any maintenance.
- Remove Filter Modules: The filtration media is housed in separate modules. These can be easily removed while the main filter bracket remains in place within the aquarium.

- Clean Filter Media: Rinse mechanical filter sponges (e.g., coarse sponges) in old aquarium water to preserve beneficial bacteria. Replace chemical media (e.g., carbon) as recommended by the manufacturer, typically every 2-4 weeks. Biological media should only be gently rinsed if heavily clogged.
- Clean Impeller and Housing: Periodically remove the impeller and clean its chamber to ensure smooth operation and prevent blockages.
- Reassemble and Restart: Reinsert the cleaned or new filter media modules, reassemble the filter, and plug it back into the power outlet. Ensure it is fully submerged before restarting.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Filter not running or weak flow | Power disconnected, clogged impeller, clogged filter media, air in pump. | Check power connection. Disconnect power, clean impeller and housing. Clean or replace filter media. Ensure filter is fully submerged and free of air bubbles. |
| Heater not maintaining temperature | Insufficient water level, heater malfunction, incorrect temperature setting. | Ensure water level is sufficient to cover the heater completely. Verify temperature setting. If problem persists, contact support. |
| High flow rate | Diffuser/nozzle set to maximum flow. | Adjust the diffuser and water flow nozzle to reduce flow. For sensitive fish, consider directing the output between the two flow areas. |
| Unusual noise/vibration | Impeller obstruction, loose components, air in pump. | Disconnect power, check for any obstructions in the impeller or ensure all components are securely seated. Ensure filter is fully submerged and free of air. |
| Water cloudy despite filtration | Filter media saturated, insufficient biological filtration, overfeeding, new tank syndrome. | Clean or replace filter media. Perform partial water changes. Reduce feeding. Ensure proper tank cycling. |
