Tunze Turbelle NanoStream 6025 Pump (6025.000)

Design is much more than only styling of existing products: It is the expression of an idea and a concept; it opens one’s eyes. Turbelle® nanostream combines aesthetics and function. This innovative circulation pump sets new records: At a diameter of only 2.75" it enables a water flow of 660gph at an energy consumption of only 7W. The pump includes a very large strainer for the intake which prevents premature soiling. The spherical shape permits an ingenious 3D setting of the direction of flow. As a standard feature, Turbelle® nanostream is supplied with a magnetic holder (holds up to 1/2" thickness), which enables uncomplicated attachment at any position on the aquarium pane. 

  • New Generation with Titanium Alloy Shaft
  • For aquariums from 10 to 55 gallons
  • Flow rate = 740 gph
  • Energy consumption = 5W
  • Voltage/Frequency = 115V/60Hz

Works great

Pros: Easy to install, quiet

Easy to set up to provide flow for dead spots in my 90 gallon. No problem for magnet to hold pump on the thicker glass in my tank.

Small, but strong.

Have always wanted a pair of these for my nano. I've bought cheaper power heads and what not in the past. These are small and very powerful. My corals and fish are loving the currents.

Pumps get stuck

I have 2 of the Tunze 6045 (1188 gph) and they get stuck sometimes when I shut them off to feed my fish and coral. It is annoying to have to take them apart and mess with them to get them to work. Only good thing is that when they do work they use very little power and take up little space.

Solid, clean, quiet

Running for a week now in a 65 gallon FO salt aquarium. Quieted down drastically over the first couple days. One star removed for the weird flimsy grille on the output. It broke into pieces on instalation. Unusual for Tunze but my friends did the same. Not sure if it is weird manufacturer leftover from molding or a protective grille. Either way it does not cause full functionality loss, purely cosmetic.

Great product

For the money, can't beat it. Don't expect an extremely strong current, they just keep water moving in dead spots, moderate current. Would be amazing for a smaller tank, but for what I needed them for, they are perfect! I bought two for a 65g new reef setup and am very happy! Sleek design, magnetic attachment so no worries about suction cups failing and stirring sand up all over, would purchase again!

Works great

I have 2 hydor korilla 3 control pumps and just added two new 6045 tunze to clear dead spots. Definitly no noise when starting up verses korilla, and I love how quick and easy it is to adjust water movement... Would definitly recommend the product...

2 words...silent and strong.

I have always purchased the low end products when it came to power heads. This is also my first Tunze product. It is everything I had heard about the line of Tunze. It is a little on the big side for my tank but is silent and strong. I would not hesitate to tell anyone thinking of getting one of these it worth the extra money. The moment you pull it out of the box you know it is a quality product.
