- Rinsing: Rinse the aquarium, filter media, and decorative elements thoroughly with clean water. Do not use soap or detergents.
- Filter Media Installation: Install the provided filter media (foam, carbon, Biomax) into the designated compartments within the hidden rear filter section. Refer to Image 2.1 for guidance.
- Pump Installation: Place the water pump in its compartment within the rear filter section and connect it to the output nozzles.
- Substrate and Decor: Add your chosen substrate and decorations to the aquarium.
- Filling the Aquarium: Slowly fill the aquarium with dechlorinated freshwater to the recommended water line, ensuring the filter pump is submerged.
- Lid and Lighting: Place the aquarium lid on top. Connect the LED lighting unit to the lid and plug it into a suitable power outlet.
- Power On: Plug in the filter pump. Ensure all electrical connections are secure and away from water.

4. Maintenance
Regular maintenance is crucial for a healthy aquatic environment.
4.1 Filtration System Maintenance
The 3-stage filtration system requires periodic cleaning and media replacement:
- Mechanical Filtration (Foam): Rinse the foam filter regularly (weekly or bi-weekly) with old aquarium water to remove trapped debris. Replace every 2-4 weeks or when visibly degraded.
- Chemical Filtration (Carbon): Replace the activated carbon every 2-4 weeks. Carbon absorbs impurities and odors but becomes saturated over time.
- Biological Filtration (Biomax): Do not clean or replace Biomax media unless absolutely necessary, as it houses beneficial bacteria. If cleaning is required, gently rinse in old aquarium water.
Access to the filter media is through the hidden rear compartment. The easy feed top cover opening facilitates feeding without removing the entire lid.
4.2 Water Changes
Perform partial water changes (25-30% of the tank volume) weekly or bi-weekly. Use a gravel vacuum to remove debris from the substrate. Always use dechlorinated water that matches the aquarium's temperature.
4.3 Aquarium Cleaning
- Clean the interior glass surfaces as needed to remove algae using an aquarium-safe scraper or magnet cleaner.
- Wipe down the exterior surfaces with a damp cloth. Avoid abrasive cleaners.
5. Troubleshooting
This section addresses common issues you might encounter with your Fluval Flex aquarium.
