Another great JBJ product, couldn't be easier than this. Works great, a must have for anyone using a sump.
Does exactly what I wanted By Chad on 12/15/2012

This ATO does exactly what you expect it to do. JBJ gives you a few options on how you would set it up, and although I am not an expert I think they include every applicable way to work an ATO.
I have one sensor in the third chamber of my sump and the other in a bucket full of fresh RO/DI water. When the water level in the sump gets low, it fills it. If the sensor in the bucket gets triggered it stops pumping water, which saves the pump.
I paired this with a Marineland Maxi-jet 400.
UNRELIABLE FOR ME By Ron on 12/8/2012

I just got the JBJ ATO and it's doing the same thing others have reported on various forums. Randomly, sometimes as much as once an hour, the controller turns on but with in a few seconds goes into time out mode shutting the pump off. I have it set to the max, which lets it run for about 13 1/2 minutes when it's working the way it's suppose to. Some have said the aqualifter may not be drawing enough power, like the reefkeeper problem with Koralia pumps on the solid state relays. I plugged a lamp in, in addition to the aqualifter with no change. So I'm not blaming the aqualifter at this point. Power draw doesn't seem to be the problem. I believe it's a problem with the electronics of the ATO itself. I found a work around on the internet of putting a timer on the ATO using my reefkeeper. Once an hour the reefkeeper turns the ATO off and back on resetting it. This works fine, but my confidence in the ATO isn't that great since I have to manipulate it to work. If the timeout becomes frequent enough, eventually it won't keep up, and worried it will end up having some other failure. Wishing I would have went with the Tunze now, which I'll probably do, and end up almost $300 into an ATO vs $200 if I had bought the Tunze from the beginning. I love BRS, but looking at the return policy for the first time, it states warranty issues must go through the manufacturer, vs. being able to return a defective product directly to BRS. I'd like to swap it for a Tunze, rather than trying to get it fixed or replaced. So that was a disappointment also. Buy yourself a different ATO.
Many limitations, one fatal flaw for me By David on 12/2/2012

Don't be fooled by two float switches - they don't work as you'd expect. Instead of redundancy - 1 "high" switch as a backup in case the "low" switch fails or is blocked - it's just 1 switch for minimum water level and 1 switch for maximum water level (Mode B). Or 1 switch in the ATO reservoir to protect the pump from running dry (Mode A). Anyone serious about safe ATO wants redundant switches in the sump/tank. Now I have to decide if I want the Tunze or DIY with my controller.
More minor concerns are the mounting brackets for the float switches. They don't fit over the rim of my tank very well and the height setting is adjustable in only large increments.
The float switch "guards" don't look like they'd keep anything out - any small to medium size snail could get in there and block the float's motion.
All together a disaster waiting to happen.
SIMPLE LOW COST OPTION FOR ATO. SIMPLY WORKS. By Kevin on 12/2/2012
Kevin would recommend this product to a friend
I've ordered two now, one about a year ago for my main tank and now this for my pico. ATO units don't need to be complicated. They just need to do three things:
-Transfer water from a reservoir to your sump/tank.
-Not overflow your sump/tank.
-Shutoff when reservoir is empty to prevent pump failure.
This product does all three, but does not come with a pump so I'd recommend the aqualifter.

Feels a little cheap but runs like a champ. I've had one for over a year with no hiccups and just ordered another one for a frag tank.

Had this unit and really liked it at first. It seemed to work fine just as advertised. 6 months in the controller has stopped working and emptied my reserve almost causing a major disaster. I figured this was just a stuck float or something but it was not, unit no longer works. Save your money and buy the bigger dosing pump with a timer or even better allow a controller to do it for you.

Ok, so I wrote a less than glowing review of the JBJ auto-top off. I managed to do a web search and found that you have to take the unit apart to change the setting for the fail safe. Mine was set as low as it could get and my aqualifter just couldn't keep up. Once I took the unit apart and set it for the 14 minute setting, it's worked with no problem. bad design.
annoying By Jeromi on 11/11/2012

This thing does not turn my aqualifter on. It doesn't matter how I have it set up. I've heard that the aqualifter doesn't draw enough power for the JBJ to even pick up on, but I find that hard to believe. I want to use the Aqualifter because I want a slow top off, but, so far it's been worthless. I have to manually push the float switch down for it to pump any water. This is becoming more of a pain than it's worth. I was better off manually adding water every day.

This works great for ATO. It meshes well with the aqualifter
EXELLENT PRODUCT FOR A GREAT PRICE By Richard on 9/13/2012

I have had this unit on my 57 gallon tank for 1 month and love it! Easy to set up. However, I wilsh they had a manget option for the sump float switch as the suction cups don't work that well. Long story short, I made my own.
In short, I highly recommend this product. In fact, I am buying a second one right now!!
