7. Adjust the integrated heater to your desired aquarium temperature, typically between 24-28°C for most tropical fish, ensuring stable and uniform heat distribution.

Care & Maintenance Tips

• Regularly clean or replace filter media according to OASE’s recommendations to maintain peak filtration efficiency across all three stages (mechanical, biological, chemical).
• Utilize the integrated shut-off valves to easily disconnect hoses and minimize water loss during routine cleaning, simplifying the maintenance process.
• Periodically inspect all hoses and connections for any signs of wear, blockages, or potential leaks to ensure continuous, reliable operation and prevent water damage.
• Clean the impeller and motor housing when performing filter maintenance to ensure the 1000 l/h flow rate is maintained and to preserve the unit’s energy efficiency.
• Monitor the performance of the integrated 300W heater to ensure it continues to provide stable and uniform temperature control throughout your aquarium.
• Perform regular partial water changes in conjunction with filter maintenance to support overall water quality and the health of your aquatic inhabitants.
