Tunze Osmolator Nano 3152 Auto Top Off ATO

The Tunze Nano Osmolator 3152 is a water level controller with only one sensor, and works great for nano or small aquariums.

Overview:

  • Great for nano aquariums and tanks up to 55 gallons
  • Ready for installation out of the box
  • Can be installed in a cabinet filter or directly on the aquarium edge
  • Safe low voltage construction
  • Includes a metering pump, 3 meters of tubing, magnet holder, power supply, a float switch, protective shield and control unit. 
  • Suitable for aquariums up to 10 mm (0.39") thick

For safety purposes, the Osmolator 3152 includes a processor-based anti-overfill system which turns the pump off after five minutes of filling if the level has still not been reached (equal to a pumping of approximately 0.75 gallons).

The Tunze Nano Osmolator 3152 was built in Germany and includes a 2-year manufacturer warranty that excludes the float switch—which features a 6-month manufacturer warranty and is user replaceable.

For larger aquariums, check out the Tunze Osmolator Universal 3155. If you need a container to hold your top off water, the Tunze Osmolator Storage Container 5002.25 is an ideal choice.

Q
How high vertically will the pump be able to pump water.
I need to know if the pump is able to pump water over 4ft vertically. I will be running the tubing from my floor level reserve directly into my tank sitting on a stand.

The user manual states that the maximum conveying height is approximately 2 m (78.7 in.), so it should work well for you.

REVIEW
Great ATO and just as good as the full size Osmolator on smaller tanks! It takes up less room and fills fresh water reliably. The big thing you lose with the Nano version is the secondary mechanical float switch as backup...but, the good thing is from my research I’ve never heard of the optical sw...Read More

PROS
Build quality, function, dependability and cost
CONS
pump noise level (not the quietest of pumps). If used in a quiet location, the pump can be startling when it kicks on.
REVIEW
Best ATO I've tried for systems under 100G. See "Cons" for reason for 4 star rating. I haven't tried any similar products that deserve a 4 or 5 star ratings (excludes ATOs integrated into expensive Aquarium Controller Systems.

Tunze ATO Nano- Great Customer Support!

PROS
I contacted the Tunze after my warranty expired stating the pump would only work for 2 seconds then auto turn off. Roger from customer support was very helpful. In less than a week, Tunze diagnosed the controller board, and reprogrammed pump cut off from 800mA to 900mA.

I purchased this back in 2016 for my reef tank. No more lifting top-off water into the tank. I work alot and this is very handy for me.
To note, one need to prime the pump after each water source replacement. The float valve cover is usually good enough, but keep an eye on it every once in a wh...Read More

PROS
Tunze, stand by their product. I reach out to them after warranty expired in 2018. I sent it back to the company to see what's wrong as the pump shut off after 2 seconds. They took the time and reprogram the controller board since it it was set to cut off at 800mA instead of 900mA. Great Service!!!

I've bought this pump back in 2016. Keeps the tank full and has fail safe float switch. Product is still going strong after several years of being used, great product from Germany.
