  • Great ATO By on 6/18/2017

    I am new to the reef tank hobby and being well versed in freshwater i did not know an ATO was nessasary for saltwater. But after dealing with evaporation i knew i needed an ATO and this Tunze Ato is great. For the time i have had it i have had no problems at all. Got a 10 gallon brute can and it goes for 10 days without problem . Highly recommend this ATO.

  • Great product and easy instalation By on 5/18/2017

    Only had this ATO a few months now. It was very easy to install. Everything seems to be working fine no issues other than one day the alarm was going off. After only a few months of running apparently the electric I had something on it and so when I wiped it off the alarm stopped. The alarm was going off because the ATO started running and increase the water level in the song so good thing it had the secondary shut off and it shut it off that set off the alarm. Great safety feature seems to be a great ATO and I'm very happy.
  • Good quality product; easy to install By on 5/9/2017

    This ATO works very nicely and is ready to use with a few simple installation steps. It comes with everything (ie. pump and tubing) so all you have to do is drop the pump into your water reservoir, set the sensor, and plug in the ATO.
  • Loving it! By on 5/8/2017

    I was recommended this by a fellow reefer and I'm glad he did. It's quiet and i haven't had any problems with it at all, yet. I would go with anything else.
  • Works Great By on 4/20/2017

    Easy to use and setup, works great!

    I got this one in from BRS and nice easy install and works like a charm. just be careful of the magnets you get those stuck they are a pain to pull apart. tip leave them on the foam until you need to put on tank.

    It's impossible to say whether this is a quality product after only owning it for a month, it's brand new so I would fully expect it ro work and do everything as advertised. I'll just have to wait and see how it functions 2 or 3 years from now. I can say that it was easy to setup and has functioned properly so far. I purchased this ATO really just for times when I'm away from home and can't manually top off my tank. I prefer to manaually fill the tank each morning after I test the salinity. I'm going to have to either fill the ATO reservior or the tank, may as well just fill the tank. I bought this unit because it was the most expensive and had the best reviews. Time will tell if it was worth the investment.
