  • great product By kalen on 12/11/2014

    I recently bought the tunze ato and I had heard many good things about it. I did many months of research and I finally decided to buy it and replace my smart ato which was always failing. I would recommend this product to others
  • Tunze osmolator 3155 Top Off By Joe on 12/10/2014

    This is the best automatic top off system I have 3 of them on different tanks. Easy to set up plug and play. They been running for over 3 years with no problems.
  • The best By John g on 12/9/2014

    Very easy to set up and extremely accurate
  • Easy Setup By Evelio on 12/9/2014

    It was easy to set up straight out of the box. This is one of the best investments that I have made for my tank.
  • ONE WORD....WOW!!! By NASSAUREEF on 12/8/2014

    This top off is amazing very easy to setup. Don't waste your money on another brand cause it will cost you double and you will end up with the tunze , so buy it the 1st time and it will be the last one you will buy..
  • Simply perfect By Nate on 12/8/2014

    I have used two tunzes osmolators on different tanks and I have never had an issue. double back up (float sensor and auto times pump shut off) makes me not worrying about having water over flow. and all the install hardware added is always a bonus, like the return tube holder.
  • best investment i made By Andre on 12/6/2014

    My first ato and only I will buy. very happy with this ato. Easy to install
  • Love it! By Joshua on 12/5/2014

    I have had a few different ATOs but this one is by far the best I have had. Don't know why I didn't just get this one from the start.
