Review of the Tunze Nanostream 6040
We already made an unboxing of the nanostream 6040 on this website; here is a test in a real environment.
Context of usage
Since several years, I have two pumps in my 120 liters tank, one Tunze 6025 and one Tunze 6015. For me, the usage of these two pumps is as much a flow choice as to have a functional pump in case of failure of the other.
Note for 6015: It is a three-year-old model; the power of the magnet holder was provided initially proved insufficient for my 10 mm thick tank, the pump slid down to the bottom of the tank after a few minutes of operation. I alternated ½ of the magnet holder 6025 (beefier) with ½ of 6015 to avoid this inconvenience.
The test
I will introduce the replacement of the 6025 by the Tunze Turbelle nanostream 6040 and the replacement of the 6015 by the 6040. I did both tests before deciding myself.
For those who do not know it, here is a picture of the Tunze 6040 pump unpacking.
First impressions: we can see the well-protected magnet holder (no visible magnet) and I see that its effectiveness will be perfect for my tank 10 mm thick. Another good point, the lengths of the electrical cables are generous, this between the pump and the controller and between the transformer and the controller. Also, note that the transformer does not take up much place.
The pump dimensions are very reduced.
Below, here are some before and after photos to replace my 6025 (left in photo) or 6015 (right in photo).
Before
After (the two tests)
We can clearly see the gain for place. This, in particular on the depth.
With the thinner, I had the possibility to lowest positions for the 6015 replacement case. The stream being rather diagonally upward, the low position still generates a flow of up to the surface
The various possible settings
A printed leaflet describing the installation and the various possible settings is provided as multilingual. Read the few pages of the manual is advisable to fully understand the different possibilities.
The controller allows the wave simulation, an oscillatory mixing with automatic detection of the oscillation frequency for the tank. There is a pause function for feeding. A Moonlight photocell can be added to lower the flow during the night, for example. It is possible to manage several pumps via a Multi-Controller which offers a variety of other opportunities (waves simulation oscillation flow …). See leaflet for detailed description of the possibilities! I do not have the sensor, so I do not make the night operation test.
Preparation of establishment
Before the implementation, I did some testing of the pump in a bucket freshwater. It allowed me to better understand the various settings, especially for the power. I have also been able to get a first feel for the flow of water. I did not wanted to risk spilling water on the floor due to the power margin relative to the size of my tank, I did well.
Settings chosen
I use the pump in the basic mode. I did not use the wave simulation, for example, my tank is square it does not seem too appropriate (besides automatic setup did not something very convincing). Moreover, I do not want to change things too suddenly in this tank that already has a few years. I will see in the future and cravings that can evolves (there are tons of setting options, such ripples).
During the initial replacement of the 6025, I had dropped the pump position because the flow was moving a little too much the surface and generated little bubble through a whirlwind in front of the tank! For the replacement of the 6015 I have no problem because I have set lower the pump and the power is set lower. The power setting is very convenient for simple adaptation to various uses. As the button ‘food’, that cuts the brewing.
In the case of my replacement pump, on the right, I have a clear visual gain (and space), for the front view.
I made some test of the ‘pulse’ mode. In this video, you will see some usages.
Final choice
For the moment I decide to keep the 6040 and the 6025 (for safety; I am cautious and this reassures me), even if for the flow point of view, the 6040 could largely ensure for the full tank!
I have not tested, but I like as well
The 6040 can be powered by 10-24 V continues (via Safety connector 6105.30) this can be very interesting for the case of electrical failure since it allows normal use with main power and switching on the use of a battery in case power failure. I see that, perhaps, one day!
I like
- The pump is very small and powerful
- Flow control on a wide range (200 l/h à 4500 l/h)
- Possible flow setting: with or without deflector for vertical & horizontal directional side
- A lot of possible setting so that everyone finds his or its uses
- The cables lengths are very significant
- The magnet Holder is well protected and effective for glass up to 15 mm
I like less
- The reflector does not provide for adjustment between the vertical & horizontal (the flow is vertical without the reflector or diagonal upwards with)
Note: there is also the Tunze 6020 belongs to this new series of Tunze’s pumps. If you do not need all the settings and the flow rate corresponds to the expectation, we can use this little space-saving pump for cheap.
Overall, I love this pump!
