Really good value By R-1 on 1/25/2014

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.

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.

Have used this ATO for 2 1/2 years and have never had a single issue. The floats still work. I use with an aqua lifter. I also have it set in the mystery 3rd mode that I had to find online this is the way I recommend using it, this mode has a float switch turned upside down for fill when the water gets too low and stop when it turns the float switch to off, the second float is positioned above and functions as a universal off in the case that the first float switch gets stuck in the on position.
I happen to like the timed safety backup just in case the first backup safety fails the ATO will automatically shut off after about 15 mins of being on.

I've owned 2 of these auto top off systems. I'm currently running one on my 75 gallon mixed reef tank.. the first one i owned on this 75 lasted for 1.5 years before it bit the the dust.. the pump I'm using is aqua lifter aw-20 which is something your going to have to purchase additionally so keep that in mind when doing your price comparisons as well.. the first thing to go on these things are the float valves. the sensor just stops working after a while so i suggest if you do plan on buying this don't use both float valves if you don't have to…use one on the return portion of your tank and wait for it to clunk out before you use the other one.. when the first one clonks out just purchase another float valve and wire the new one up to the clonked out ones connectors.. do the same when the your second one clonks out.. my first one clonked out around the 6 month mark the second one clonked out around the same.. the unit itself died in 1.5 years.. had 3 extra float valves so i just ordered another one.. the tank I'm running this on is a basic tank i plan on passing on to a friend and made no sense for me to invest in a quality ato that I'm not planning to keep for ever.. I'm doing a 120 48x24x24 with all the bells and whistles and I'm running a tunze osmolator on that tank.. no review on it bc i still haven't used it yet..

this product isn't terrible by no means but it is cheaply made. the feature i love and hate it has a timer in it. so if you don't have a strong enough pump for the water it will stop itself because it has been on to long. I recommend not to use a aqualifter for . i use a pico evo-mag 180. since then no hiccups with the top off system
Poor reliability By Will on 1/4/2014

This has frequently failed for me. There are no snails debris or critters in my sump that would prevent the float switch from falling but it still fails from time to time. Frequently I have to reset the whole unit.

Unadvertised features will stop this device By red on 11/23/2013

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 6/22/2013

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.
