3. Componenti finitiview
The EDEN 328 Internal Filter consists of several key components designed for optimal performance.
- Unità pompa: Houses the motor and impeller for water circulation.
- Filter Chambers: Multiple compartments for various filter media.
- Spugne filtranti: For mechanical filtration of coarse particles.
- Venturi Nozzles: For oxygen enrichment of the water.
- Rotating Water Outlet: Patented design to create natural water currents.
- Ventose: For secure attachment to the aquarium glass.

4. Configurazione e installazione
- Preparare il mezzo filtrante: The filter comes with two filter sponges for mechanical filtration. The two subsequent filtration chambers can be filled with additional mechanical or biological filter media (e.g., activated carbon, ceramic rings) as desired. Ensure media is rinsed thoroughly before placement.
- Assemblare il filtro: Ensure all components are securely fitted. Attach the Venturi nozzle and air tube if oxygenation is desired.
- Clean Aquarium Wall: Before installation, thoroughly clean the inner surface of the aquarium glass where the filter will be placed to ensure optimal suction cup adhesion.
- Filtro posizione: Submerge the filter completely in the aquarium water. Position it vertically, ensuring the water outlet is above the water surface if using the Venturi function, or slightly below for quieter operation and surface agitation.
- Collega all'acquario: Press the suction cups firmly against the clean aquarium glass to secure the filter in place.
- Connetti alimentazione: Once the filter is securely installed and fully submerged, connect the power plug to a suitable electrical outlet.

5. Funzionamento
- Avvio del filtro: After connecting to power, the filter will immediately begin pumping water.
- Regolazione del flusso dell'acqua: The EDEN 328 features an adjustable flow rate. Refer to the diagram on the filter unit for specific adjustment mechanisms.
- Venturi Oxygenation: If using the Venturi nozzle, ensure the air tube is positioned above the water surface. Adjust the air intake for desired oxygen bubble production.
- Water Outlet Rotation: The patented rotating water outlet can be adjusted to direct water flow, creating natural currents within the aquarium.
6. Manutenzione
Regular maintenance is crucial for the longevity and efficiency of your filter and the health of your aquarium.
- Scollegare l'alimentazione: Prima di effettuare qualsiasi operazione di manutenzione, scollegare sempre il filtro dalla presa di corrente.
- Rimuovi filtro: Carefully detach the filter from the aquarium glass.
- Smontare: Gently separate the filter chambers and remove the filter media.
- Pulire le spugne del filtro: Rinse the filter sponges thoroughly in old aquarium water (from a water change) to preserve beneficial bacteria. Do not use tap water directly, as chlorine can kill these bacteria. Replace sponges when they become too degraded.
- Girante pulita: Periodically remove the impeller from the pump unit and clean it and its housing to prevent blockages and maintain optimal flow.
- Clean Filter Chambers: Rinse the filter chambers and other plastic parts with aquarium water or dechlorinated tap water.
- Sostituisci supporto: Replace activated carbon every 2-4 weeks. Biological media (ceramic rings) should only be rinsed gently in old aquarium water and replaced only if physically degraded.
- Rimontare e reinstallare: Reassemble the filter, ensuring all parts are correctly fitted. Reinstall in the aquarium and reconnect power.
