The Tunze Turbelle® nanostream® 6020 delivers a gentle circulation and significantly more power than their sleek exterior design suggests. This type of very compact circulation pumps for aquariums from 40 to 250 liters (10.6 to 66 USgal.) can be easily hidden behind a decoration, and thus ensure the harmonious overall appearance of a small aquarium, absolutely perfect for aquascaping. Thanks to the special flow deflector and Magnet holder, the wide waterjet is 3D adjustable at the pump outlet. Through the Silence holder they do not touch the aquarium glass pane directly and are therefore unable to transmit vibrations, which makes it one of the quietest pumps available on the market.
