Just what I needed! By Jason on 11/22/2015

For about $30 more, you can purchase a JBJ ATO system if you won't want to go with a "do-it-yourself" option. I, however, wanted to customize the system to my needs. Here are some points to consider:
1: can be setup several different ways, with a single switch, two switches, or three. This allows both an initial cutoff, a secondary cutoff in case the first float switch gets stuck in the 'on' position, as well as a switch that can flip if your reservoir is empty. The JBJ only allows two switches--this can run all three.
2: I was able to splice additional wire lengths to customize the reach and fit. In general, I don't want the system right against the sump--I want the sensors to have a long reach into the tank and locate my system elsewhere. I can use a longer power cord as well. The mouldable mounting bracket allows you to setup specifically to your sumps needs.
3: there is a 'click' when turning on and off, which several reviewers have mentioned. However, when in the project box (the case for the system), it is barely audible. This is, however, useful when testing your project to ensure it is triggering on and off properly.
4: why not just splice a float switch onto your topoff pump power supply and be done with it? Because a) you will have a 120V line running through your tank that is not rated to handle it, and b) the float switches are not build to handle that current (or even close).
5: by combining an RODI reservoir (in my case, a 5-gallon RODI bucket) with a float valve and auto-shutoff, as well as a pump of your choice (in my case, an aqualifter pump), I have never had to run extra buckets, turn my RODI off, or top my tank off again. Even when we're away for days, the water level stays perfectly even.
6: I combined everything in (5) into a 12-gallon tupperware bin next to my tank. RODI in and water out are run through 1/4 ID rubber grommets. Pump and ATO are on a drainable shelf and all hooked to a surge protector that will trip if wet. It's well packed, clean, and runs well!
Good, Inexpensive Alternative By Geoff on 9/28/2015

I've been running this ATO for about 6 months now. Haven't had any issues. The instructions are detailed and easy to follow. The one thing I would say you need to be aware of is the relay makes a loud clicking noise when it engages. Mine can be heard from several rooms away.
Save the money, DIY. By ChuckD on 6/30/2015

Was a little hesitant about building my own ATO (actually considered selling the kit and buying a pre-made unit) but by the time I put it together I had read through the instructions so many times I had them memorized. Turned out to be a piece of cake.
Only issue I fretted over was the height of the mold-a-holder as I wasn't sure where the water level would be on the float switch (just fyi: it's just about even with the bottom of the snail guard lid) but I left the extra material on, test fitted and re-heated and got it squared away.
Definitely would buy this again if the need ever arises.

I have had the same unit in service for 6 perfect years of service. I love the aquahub ato. I am building a second tank soon and will be getting another one of these.
Help for Greg on loud buzzing By Aquahub.com on 10/27/2014
Aquahub.com would recommend this product to a friend
The buzzing is probably caused by having a pump or other source of magnetic interference too close to the float switch. As the pump rotates, the magnet inside creates rapid waves of magnetic force which cause the reed switch to flutter and the relay to go on and off very rapidly which creates the annoying buzzing sound. Move the pump as far away from the float switch as possible, this should solve the problem. If the buzzing has already caused the relay to fail, write us at Aquahub and we will send you a new relay. Thanks
Overall good auto top off, but very loud and annoying! By Greg on 10/5/2014
Greg wouldn't recommend this product to a friend
For the money the auto top off has worked good. but the unit is pretty loud as it turns on and off repeatedly.
My tank is in our living room and its REALLY hard to ignore the continuous buzzing sound it makes every time the float switch makes the unit kick on. I wish there was a fix because at times it can be kicking on every few seconds
Great little kit By JR on 8/20/2014

I put this kit together just a few days shy of going on vacation (yes, the ultimate test) and paired it up with a two gallon bucket of RODI and a tiny fountain pump. I am super happy at the results. My sump has yet to sway from the top off point and just like putting a model car together it was fun and gave you the options to really build your own design. Great and affordable kit.
Works Great and Cost Effective! By Shaun on 7/9/2014

When I decided to finally add ATO to my sump (which I should have done a while ago looking back), I was looking for a simple and cost effective solution as I needed to keep to my budget for this upgrade. After considering all the options, and the price tags, this was the clear winner! Paired with a TOM Aqua Lifter pump, this has been a flawless solution. Easy to build using the provided instructions, I had it built and in operation within an hour. Molding the float mount took the longest but was simple though tedious. The components provided in the box seem of quality, but will be easily and economically replaceable if they become defective. This would not be possible with more commercial ATOs in most cases and I prefer self repair. Would definitely buy again if I had a need for a second one.
good system if it's done right. By The guy from Langley British Columbia. on 2/23/2014

If you are electrically inclined there good and work well, The 12 volt part has to be carefully connected and crimped with a proper crimper for sound operation and connection to the relay. Other reviews I've read said they quit working and I think they have not made sound connections which on low voltage is very important, my background is in HVAC and controls so I know this is a very important point to make.
