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.

This is my first and probably the will be the last ATO system I will need to buy...unless I set up another reef tank of course. Forget about the "hefty" price tag, your tank is certainly worth it.
Excellent product! By Joseph on 6/1/2015

I have this setup currently for my system. While the instructions are not as straightforward as I'd like, there are plenty of videos online to learn how to set everything up. There are several ways to use this product which are part of what makes it good but also part of why the instructions are a little confusing. Nevertheless, it works great and worth the money IMO. Get it.

IT IS A PEACE OF MIND, NOT HAVING TO WORRYING IN ADDING WATER AND SALT EVERY TIME IT GETS LOW.
