    Like others have said. Its okay I guess but don't trust it with your tank. It will randomly decide to stop working and then your tank won't fill. If you're always around its not terrible but when you work 80 hours a week like me then you quickly get your tank 10 gallons of water short and with a salinity through the roof.
  • As advertised fits in back of JBJ 6 Gallon By on 6/24/2016

    I use this in my JBJ 6 gallon reef tank. The float sensor fits in the middle back compartment after I removed the original media.
  • Decent ATO when it works, not reliable for long trips By on 6/2/2016

    I've had this ATO about 2.5 years now. It's decently reliable, however, sometimes it just stops working, its like it will get past the float valve and just not try to fill any more. Usually I can go 3-4 days with it working, and then it stops, I'll come home after not being there for 5 days and I'm about to run dry in my pump. It's a shame, since I'd like to be able to leave for 5+ days without worrying about the tank running dry. I would recommend it for people who had time and are around enough to catch it not working. I've swapped float sensors, but went back to the original, because the new one shorted out or something.
  • No go By on 5/21/2016

    Ive bought 3 of these. None of them lasted longer than 6 months. 1 blew it's board in 60 days, the other two stopped recognizing the float switches. Jbj did send me a new head unit but after 3 failed controllers I have completely lost faith in the products this company pushes.

    these just don't last.
  • Positive Review By on 2/16/2016

    I am running the JBJ ATO on my 27 gallon cube with the eshopps sump. I highly recommend watching the videos and setting the ATO with Sensor A triggering the pump and flipping Sensor B around to shut the pump off if the water volume gets to high in the sump.
  • Money Well Spent By on 1/3/2016

    Easy setup, straightforward indicators, and well priced. I haven't had any issues at all in months of use, and little to no build-up on the floats. I do still clean them with my sump maintenance, and splash some water on them to stave off salt creep now and again. I do like having the second float as an off switch as recommend by the BRS video. Will buy again if I need another.
  • Same story different person By on 12/22/2015

    I recently had this product working well for about a month or two. Switched it to a different tank and now the red light goes on for instilling water and does not go off, switched sensors, power on and off, no kinks in sensors, it just does not work. Very disappointing. Had a great start
  • Nice By on 12/19/2015

    I purchased this with a nice pump very reliable and cost effective
  • Disappointed By on 12/1/2015

    Biggest thing I found was that if I have power outages even for a minute or two when the power comes back on the ATO turns on the pump for about 10 seconds "no matter what the water level is". If you have several power stops and starts like when they are trying to get the power on after a storm you could end up with a flood.
