Unadvertised features will stop this device By red on 11/23/13

if the float switch/pump is toggled on longer than jbj feels is necessary, the unit will lock out. And you will have to reset the device by power cycling it.

Simple installation. If using in sump don't allow snails to enter your return section.

I've been using this auto top off for the past year and I've not had any problems with it. This handy piece of equipment has not only saved me a lot of time, but it has been an essential part in maintaining stable parameters in my tank.

Had mine a year so far and still working great, I use mine with a Tom's aqualifter pump for my top off.
Pretty Good By Kyle on 6/22/13

It took me a minute to figure out with all the wires and stuff, but it works pretty well. The floats seem kind of cheap though.

This works perfectly, easy to use, easy to set up. Very reliable, another great plug n play item. Bought 2 of these, one for each tank. As always BRS has the best price around. Also recommend the auqua lifter pump...
Awesome By Frederick on 5/16/13

This ATO is great. Although it uses float valves it is perfect when it comes to mantaining the level in my sump. I have a aqualifter pump hooked up to it.

This is a great product for the price. I use it on my 40 breeder QT tank and have had no problems.

Tends to stick By David on 4/14/13
David wouldn't recommend this product to a friend
For the money it is an ok ATO however the floats tend to stick and will mess with your salinity. I had to put both floats in the sump as a safe guard so that if one float fails the other will turn off the ATO. I have had multiple instances were it has nearly overflowed my sump.
Good, simple ATO By bruce on 4/13/13

The JBJ A.T.O. system is a good, simple auto top system. I have been using it with absolutely no problems. My only complaint is I wish there were more mounting options included with the sensors. I think if you are using a traditional system, you would have no problem. My water storage is a little unique, so I had to modify the sensor bracket.

I love JBJ product. This ATO is well designed and easy to set up. I will order another to use from my freshwater tank.
I have had the unit work well in my 20 gal nano tank but sometimes the sensor gets invaded by a snail and causes the tank to overfill and my salinity goes to crap! By Louy on 3/27/13
Louy would recommend this product to a friend
What this unit really needs is a way to double up on the fill sensors. That way if a snail gives one a ride it would not cause the tank to overfill and ruin your salinity. In other words, the unit would have to recognize when both sensors are calling for top off water to come on.

The JBJ ATO is a very simple design. It has a nice looking control module that nicely mounts to the inside of my tank stand, hidden but still up off anything that might get wet. The only drawback I had was that there was no good way to mount one of the sensors in my RODI reservoir so it kind of just floats around in it.
Grea, with small set-back By Tommer on 3/12/13
Tommer would recommend this product to a friend
This is a great ATO switch. The only thing that I don't like is that the ATO checks every ten seconds to see if it is full and then turns off. So on a smaller tank that not turning off for possibly 10 seconds might cause salinity swings.
Works Perfectly By djwally13 on 3/11/13

I installed the JBJ ATO over the weekend, it doesnt come with a pump so I purchased a Toms Aqua lifter pump from my local fish store. The unit works perfectly, I check my water level every morning and the level is always at the line I drew on the side of my sump.
Worth the $ By shirtlessbill on 3/1/13

pretty simple idea and thus simple enough to instal. The only complaint I have with this is there arent any instructions in the manual describing the level at which the floats are activated. took me a few minutes to find the "sweet spot".
Other than that this has been a worthy purchase. keeping my SG steady as opposed to dumping a gallon of water everyday is the first step in keeping a healthy reef. Many thanks to JBJ

I have had this on one of my tanks with a Toms aqualifter for about 1 year now. Has always worked flawlessly, the aqualifter is a perfect pump for it as its quite,doesnt back siphon, there is no danger of burning it up either. the JBJ controller is easily adjusted for sump level and pump maximum run time.I Would recommend this for anyone looking for a reliable auto top off system

Way cheaper than competition but does not show in its quality. Works great so far and does what it needs to do..top off.

Low cost is nice, but in this case you get what you pay for, & I'd rather pay a little more for an important function.
Went on vacation for a week, thank God I had a tank sitter - he found the sump water level dangerously low 3 days into my vacation, with the return pump spouting tons of bubbles into the display tank. Good thing the return pump didn't run dry - would've fried it. Could've gone the opposite way, with the ATO pump running until it overflowed the sump!
Randomly it'll quit working - pump light is on but pump not engaged, confirmed the pump is fully functional. ATO box has to be powered off & back on, usually it'll reset back to normal the first time it's power-cycled.
Update-Bad Buy By Ron on 12/28/12
Ron wouldn't recommend this product to a friend
This is an update to my review below. Initially was having problems with it automatically timing out randomly when it would turn the aqualifter on. Was leaving for vaction for three weeks and had no time to get a replacement. Worked around it by having the reefkeeper turn it off an reset it every 45 minutes. I've been monitoring it by cam while I'm on vacation. 10 days in, I wake up this morning and log in and one of my water alarms is going off. It has failed now in the on position. Every 45 minutes when the reefkeeper rests it, it's kicking on for the max of 14 before it times out. Can't tell if my floor is flooded yet and had to make an emergency call to a friend that's been checking on the tank to head over and unplug the damn thing. Total junk, thanks JBJ. If you are using this, I highly recommend you don't rely on it to go on vacation.
