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.

Had the Osmolator Nano running for a little over a week and so far, everything is working well. The only issue I've run into is that the exterior magnet is too large for rimmed aquariums. The outside magnet has to sit over the tank's plastic rim, which is working so far, but means that the magnetic force holding the sensor in place is weaker than it otherwise would be. Not the manufacturer's fault, but something to keep in mind if you plan to use it on a rimmed tank.Hide
PROS
Simple, effective after modification for my needs
CONS
Terrible design flaws

I purchased the nano for my first reef tank and I have a few issues with the design.
First off, if you have a rimmed tank and want to keep the water level ABOVE the glass, you need to rig the sensor housing yourself. It has 4 clips and in order to move it up you are effectively using 2 out of the 4 clips which makes it unstable. I had to glue it in place which makes it an ordeal to clean.
Secondly, the magnet is way too powerful which attracts the sensor itself and may cause it to lock up. MAJOR DESIGN FLAW! Furthermore, depending on which way you place the magnet (in my case the 2 magnets aren't concentric in order to account for the rim), the polarity REVERSES the sensor meaning that off becomes on and vice versa. Thank god I realized this immediately and reversed the magnet's orientation which fixed the issue.
I hope Tunze re-designs this in the future because it could be so much better than what it is.
With much modification I finally got it to work.Hide

Just a forewarning: this review is not about marine depot. This is strictly my experience with the product.
I purchased the ATO about 4 weeks ago, set it up and never saw a drop of water come out the other end to fill up my sump. Yes, I tried all the tricks in the book (I spoke with customer service) and it did nothing. The pump is also very loud (even suspended, not touching any walls) and very cumbersome--there are enough connecting wires to swing from tree to tree with George . I've already replaced it with a more reliable ATO. The Tunze is where it belongs--in the trash. Thanks for nothing!Hide
