Do not screw around with the others, This one does what it says, It keeps my Sump right were I set it, I have a 40 gal sump and if it looses less than a couple of pints it kicks on and tops off..Easy to install

Great auto top of package, very easy to install and get set up. Pump is a little loud for how small it is (only hear it when in the room, which i like since I know it is working). The price is a little high, but totally worth it once you see it in person and have it setup. Would definitely buy again.

Hands down the best ATO, I have every owned and I can't see myself using anything other than this product. Wrongs flawlessly and most definitely it put me at ease not having to worry about adding water or flooding my sump.

After we finally got our tank set-up, I was amazed at the amount of evaporation from day to day. Being new to the hobby, I was concerned with maintaining stable water parameters. . I watched all the videos, researched the high tech models to the DIY versions, and decided the Tunze would be the ATO for our system. Since it's installation it has been performed flawless. I highly recommend this product.

This thing works great!! A little pricy compared to other top off brands but very dependable and unlikely to fail. I would recommend this product over all the other ones on the market. Easy to install too!

The Tunze 3155 Auto Top Off system is the best there is. This is my second 3155 system, just installed on my new 185 gal tank build. My first 3155 system (on my first,180 gal, tank build) continues to function perfectly, with no issues, after more than 3 years of service.

Loving my Tunze ATO 3155 By A.J. on 7/13/2015

After a fair amount of research and reading many customer reviews I pulled the trigger and bought the 3155. Works perfect and only took a few min to set up. It really take the stress out of traveling, not having to worry about your water level. ALSO - has kept my salinity rock solid for over 3 months now, which my corals are loving!!

My ato quit working. Contacted tunze and they had me send it in. Long story short my pump went bad and burned out the controller unit. I had to buy a new pump but even though my controller unit was out of warranty they replaced it for free.

This works great and the two different sensors are awesome. I even plumbed this to feed my two foot tall DIY kalk reactor and it feeds the reactor with no issues.
