Osmolator Nano 3152 Auto Top Off
Introducing the little brother to the Tunze Osmolator, one of the industry’s most trusted automatic water top-off device and BRS Recommended. Designed specifically for smaller aquariums, roughly 50 gallons and under, the Osmolator Nano 3152 is a slimmed down version of the full sized 3155. It includes a processor-based anti-overfill system which turns the pump off if after five minutes of filling the level has still not been reached. The Osmolator Nano includes the control unit, low voltage (6V) pump, power adapter, 3m hose, magnet mount and protective cover.
- Max Head Height: 7.0 ft
- Tubing Diameter: 7mm OD | 4mm ID
- Tubing Length: 2 Meters
- Magnetic holder for sensors up to 10mm or .39"
If you need a pump rated for higher head pressure, check out Tunze's Turbelle High Jet Pump designed to replace the stock osmolator pump
First question, how loud is it? Would it be disturbing while sleeping?
Second question, could I put it on a timer so it would only have power during the day so it wouldn’t come on while I’m sleeping?
They will both be able to fit back there.
Thank you for reaching out to us. The pump is approximately 4"x2".
Please let us know if you need anything further and take care!
While it may be sufficient for a tank of that size, depending on head height the pump has to push against, it does have more limited capacity and safeties set up for small tanks, so we don't generally recommend this one for tanks over 50 gallons.
Have a great day!
That is a valid concern and if you are keeping SPS in the 10 gallon then we would suggest looking into the Osmolator 3155, however for most fish, and other corals like softies and LPS the Osmolator nano will work just fine. Since the return pump compartment is much smaller than larger tanks, when water evaporates it will move the water level pretty quickly and activate the float switch which is pretty sensitive.
The distance between the float being triggered and off is between 1/4" to 1/3" Feel free to let us know if you have any further questions!
You can always try implementing a large magnet to ensure the hold is stronger. Other than that, there are some more permanent applications such as small amount of super glue. In any case your best bet will be to contact TUNZE and see if they have any tips or tricks.

Other then the container the kit really comes with everything you need to get started. The pump has a max head height of about 7ft.
What's the main differences between the nano and the 3155? Also, would be possible to upgrade in the future without having to buy the whole thing?
The nano osmolator is just a simple float switch and that is it. The 3155 has the dual level control with the optical eye for primary control and the float switch emergency backup. The 3155 offers superior redundancy.
It would not be possible to upgrade, they are entirely different units.
