  • Good for what I needed By Eric on 2/23/2015

    This is my first auto top off and it is working fine for what I have. The size is good and the pump is running great so far. I have only been using it about a week with only one small issue. That is, I can't find a way to have the pump sit level on the bottom of my reservoir. I think it will just take some time for the hoses and cables to stretch out. Overall, good buy for me though.
  • Dosn't fit rimmed tanks very well By Adam on 2/19/2015

    If you have a top rimmed tank this will still work but it will sit low in the tank, making the waterline below the rim. Contacting Tunze now to see what they are going to do about it if anything. Love their products but the mount for the float switch needs to go back to the drawing board. So as of now I either have to deal with the low water line or fabricate a custom mount. If the float switch fit better I would have given it a 5 star.
  • Nice auto top off By Todd on 2/8/2015

    Easy to set up and works great. My only complaint is that it needs a suction cup or something so that is attaches to the bucket as it just lays on its side without this
  • Good for a few months By Casey on 12/20/2014

    My second Ato has stopped working. When the unit works, it's great.
    When the first one stopped working, I reached out to BRS and Tunze. I learned that I was basically S.O.L without sending the unit back to them. I just decided to spend the money and buy a replacement.

    That was a workable plan for a few months until the second unit died on me. I've decided not to buy another. I'd rather pour the RO water in myself than purchase yet another unreliable model from BRS. I hope they find a more reliable nano ATO to promote.
  • Works well fills need By Thomas on 12/9/2014

    Bought this to top off my nano tank. Set up was easy and does a good job maintaining water level. Lot less hastle than topping of tank daily and keeps salinity more stable
  • Can't imagine how I lived without this thing By Sean on 12/4/2014

    No more lugging around jugs every other day, now it's only once every couple weeks! :) This is a huge upgrade and peace of mind. I have a small tank so this is huge in helping me keep my water parameters stabilized. This is a must-have for smaller reef tanks for people serious about their corals.
  • Works great By Meaton on 11/19/2014

    Perfect for my nano cube 28G reef tank
  • Compact. Works well. By Joseph on 10/29/2014

    The unit is very compact, works well, and maintains your water level with frequent small top offs.

    My only complaint is the pump doesn't have a suction or bracket so that it sticks to the bottom/side of your reservoir bucket.
  • Replaced Hydro-fill By peter on 10/7/2014

    I owned the IM Hydro-fill for about 6 months when the controller went out. I've only had the Tunze running for a couple of weeks but I like it better already. Triggers from slight water level drops and I like the idea of the built-in fail safe.
    Only complaint is the pump is pretty loud.
  • 14days Dead By Richard on 9/12/2014

    problem for the controller pump not working
