  • Even a caveman can do it! By Ed on 6/1/2015

    Easy setup, Works like clockwork! no more salinity variability, Woohoo! I use a 2.5 Gal reservoir and I have plenty of water for 1 week of top-off!
  • Painless set up works great!! By Amin on 4/27/2015

    This ato work as advertised. Its easy to set up and helps keep my parameters in check!!
  • Convenient By Mark on 3/26/2015

    I added this to a rimmed 29 gallon tank. In order to keep the water level above the outside trim I had to cut part of the inner rim off to raise the magnet and float switch. This wasn't necessarily an issue because I knew I was going to have to do that before I bought it. Just something to be aware of. I find that it will turn on and replace almost exactly the amount of water I had been adding manually each evening so that's nice. Since it's on the main display it doesn't turn on very frequently. The pump is audible but not terribly loud and it doesn't stay on for long. I actually like that I can hear it. I know it's working! An issue I have been having is due to the setup of my tank I had to place it near the hob skimmer and bubbles from the outlet on the skimmer have a tendency to get trapped under the float and make it not operate correctly. It's not a huge problem and could be avoided by placing the float farther away from something that produces bubbles. I also have a wavemaker that can make the pump turn on and off from the waves it produces. Again that can be addressed by creating less waves or putting the wavemaker and/or ato on a timer. I'd recommend this because it works pretty good and has a fairly small footprint if you want to keep it in a display tank. If you have a sump the issues I've had probably wouldn't exist. There might be some better ones out there but it suits me for now.
  • GREAT SO FAR By MARK on 3/25/2015

    I AM THE OWNER OF THE RED SEA MAX 130 C. THE VARYING WATER LEVEL IN THE SUMP HAS MADE THE OPERATION OF MY SKIMMER A NIGHT MARE! THE ADDITION OF THE NANO 3152 KEEPS A CONSTANT LEVEL IN THE SUMP AND SOLVED MY SKIMMER WOES. SET UP WAS EASY. I SUSPEND THE PUMP JUST ABOVE OF THE FILL CONTAINER BOTTOM AND IT WORKS GREAT.
  • 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
