The Voyager Nano from Sicce was developed with silent operation and durability in mind. Revolutionary Sicce Technology includes an auto-cleaning/lubricating system and vibration absorbing magnet mount. Silent operation - Sicce has some of the quietest pumps on the market to date, and the Voyager Nano is no exception . Safe - A fine-slotted protection grid ensures that your fish and inverts will remain safe and protected from the impeller. Adaptability - Ability to be connected to an ON/OFF controller like a ReefKeeper, Apex, timer, or the Sicce Wave Surfer for natural water movement. Self Cleaning and Lubricating - Water is forced into the impeller chamber to keep it lubricated and clean of debris, reducing maintenance, extending pump life, and keeping the pump running cooler. Adjustable - The included vibration dampening magnetic mount swivels to allow complete control over where your flow is being directed.
