The new Tunze Turbelle Nanostream 6020 pumps were first introduced to the public in May, at Interzoo 2014 in Nuremberg, Germany. Today, I am excited to have the opportunity to test and review it for you.

The Nanostream 6020 was one of the most interesting new products at Interzoo 2014. It has a unique vertical design, which allows it to be placed behind live rock in the home aquarium.

The pump is quite small, measuring 2.5 x 2.4 x 2.8 inches, and it has a decent fixed flow of 660 gal/hours.

These pumps can easily be hidden in both small and large tanks, and are ideal for recirculating water behind the rocks, which is how I am currently using mine.

In comparison, the tunze Nanostream 6095 has a 2,510 gal/h output with a power consumption of 21 watts, or 120 gph per watt, quite a big difference from the tunze Nanostream 6020.

Here is the pump held vertically, with the blue Silent Blocks to dampen the noise. This is a very quiet instrument, as are all the tunze recirculating pumps.

The pump is sold with a magnet attachment, which will attach to glass up to 12 mm thick in Italy and .59 inches in the United States, and the price is 37.30 euro in Italy and $42.92 US Dollars in the United States.

In a couple of months I will finish my in depth review and I will share it with you here.
