  • Good System, but tricky! By Rod on 4/9/14

    Love this reliable system, but had problems for months trying to get it to work right. Finally realized that sump water was back siphoning back to the fresh water container ( 5 gal bucket) after the pump shut off. Had many friends look at the system trying to figure it out, but nobody detected the reverse siphon. After raising the tubing out of the water in sump, it has worked great.
  • EXCELLENT!! By Lawrence on 4/7/14

    I've had mine for just over a year. Helps keep my Sump water level in check... works perfect right out of the box. No problems at all.
  • automate for best results By Michael on 3/18/14

    After automating my top off, my tank has been much more stable and growth rates have increased. I recommend cleaning the sensors every couple of months to avoid salt build up that can cause a failure.
  • Disappointing By TankLady on 2/13/14

    I used one float switch at a time, each failed after a couple of months. Additionally the unit itself freezes occasionally. Needing to be unplugged and plugged back in to make it work.
  • Not worth the money By jerry on 2/9/14

    have to keep resetting can never keep proper water level in my sump

  • Works good for Cheap ATO By Redfish on 2/5/14

    I have two of these units one on a 275 gallon tank and another on a 120 gallon tank. They are cheap and work well. I am using lime water with these and have had no problems to date.
  • works as advertised By Michael on 2/2/14

    Recieved prouduct for christmas. I paired it with a aqualifter pump. The setup was easy and the instructions were to the point and easy to understand. All in all good product for the $$
  • Really good value By R-1 on 1/26/14

    I'm using the ATO to feed the sump in a wet/dry filter. Float positioning was simple using the brackets supplied. So far so good. Aquahub makes a DIY version (which I used as a return pump emergency stop) that is easy to build but probably not for everybody.
    The floats, btw, are the same in both the Aquahub and JBJ systems.
  • Great to start with. By Red7Xero on 1/21/14

    My first one has been working for over 1 yr now with no problems. I grabbed another recently for to manage my RO/DI unit and found out it has a timer inside, which you can dial to 14 mins. So if you are planning to buy this for anything that takes longer to fill than 14 mins, choose another product.
    Thanks again BRS.
