2. Sicherheitshinweise
Always observe basic safety precautions to reduce the risk of fire, electric shock, or injury to persons. This includes:
- Ensure the aquarium is placed on a sturdy, level surface capable of supporting its full weight when filled with water.
- Betreiben Sie kein Gerät, wenn das Kabel oder der Stecker beschädigt ist, wenn es Fehlfunktionen aufweist oder auf irgendeine Weise heruntergefallen oder beschädigt wurde.
- To avoid the possibility of the appliance plug or receptacle getting wet, position the aquarium to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug.
- A 'drip loop' should be arranged for each cord connecting an aquarium appliance to a receptacle. The drip loop is the part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water from traveling along the cord and coming into contact with the receptacle.
- Never pull the cord to unplug from the outlet. Grasp the plug and pull to disconnect.
- Ziehen Sie bei Nichtgebrauch, vor dem Anbringen oder Abnehmen von Teilen und vor der Reinigung immer den Netzstecker aus der Steckdose.
- Dieses Gerät ist nur für den Hausgebrauch bestimmt.

4. Einrichtung
Follow these steps for the initial setup of your Fluval Flex aquarium:
- Platzierung: Choose a suitable location for your aquarium. Ensure the surface is strong enough to support the weight of the filled aquarium (approximately 90 lbs for 9 gallons of water plus substrate and decorations). The location should be away from direct sunlight, heat sources, and drafts.
- Spülen: Rinse the aquarium glass, filter media, and any decorations thoroughly with clean water. Do not use soap or detergents.
- Installation der Filtermedien: Install the provided filter media into the rear filter compartment. The typical order is: Foam (mechanical) first, followed by Activated Carbon (chemical), and then BIOMAX (biological). Refer to the diagram below for correct placement.
- Pumpeninstallation: Place the circulation pump into its designated section within the rear filter compartment. Ensure the multi-directional dual outputs are correctly attached and positioned.
- Untergrund und Dekorationen: Add your chosen substrate (gravel, sand) and decorations.
- Filling the Aquarium: Carefully fill the aquarium with dechlorinated water. Leave a small gap from the top edge to prevent overflow.
- Stromanschluss: Connect the power adapter to the LED lighting system and the circulation pump. Ensure a drip loop is formed for all electrical cords. Plug the power adapter into a suitable electrical outlet.
- Erstinbetriebnahme: The pump and lights should now be operational. Allow the filtration system to run for at least 24-48 hours before introducing any aquatic life to allow the water to stabilize.

6. Wartung
Regelmäßige Wartung ist für ein gesundes aquatisches Ökosystem unerlässlich.
- Wasserwechsel: Perform partial water changes (25-30%) weekly or bi-weekly, depending on your aquarium's inhabitants and bioload. Always use dechlorinated water.
- Reinigung/Austausch der Filtermedien:
- Foam Filter Block: Rinse the foam block in old aquarium water during water changes to remove trapped debris. Replace every 2-4 weeks or when visibly degraded.
- Activated Carbon Insert: Replace activated carbon every 2-4 weeks. Carbon absorbs impurities and medications but becomes saturated over time.
- BIOMAX Insert: Rinse BIOMAX media gently in old aquarium water only when necessary to remove excessive sludge. Do not replace biological media unless it is severely degraded, as it houses beneficial bacteria.
- Aquarienreinigung: Clean the interior glass surfaces regularly to remove algae buildup. The easy feed top cover opening facilitates access for feeding and minor cleaning tasks.
- Pumpenwartung: Periodically check the circulation pump for blockages and clean the impeller if necessary to ensure optimal water flow.
7. Fehlerbehebung
This section addresses common issues you might encounter with your Fluval Flex aquarium.
- No Power to Lights or Pump:
- Check if the power adapter is securely plugged into both the aquarium and the wall outlet.
- Überprüfen Sie die Funktionsfähigkeit der Wandsteckdose, indem Sie ein anderes Gerät anschließen.
- Ensure the FLEXPad remote has working batteries and is pointed at the infrared remote sensor on the canopy.
- Trübes Wasser:
- Neues Tank-Syndrom: Common in new setups. Allow the biological filter to establish (cycling process). Avoid overfeeding.
- Überfütterung: Reduzieren Sie die Nahrungsmenge.
- Insufficient Filtration: Check if filter media is clogged and clean/replace as needed. Ensure the pump is operating correctly.
- Reduced Water Flow from Pump:
- Check for blockages in the pump intake or impeller. Disassemble and clean the pump.
- Ensure filter media is not excessively clogged.
- Fernbedienung reagiert nicht:
- Replace the batteries in the FLEXPad remote.
- Ensure there are no obstructions between the remote and the infrared sensor on the aquarium canopy.
