  • Great DIY purchase By on 8/17/2017

    This went together very well, and I had fun figuring out how to tailor it for my needs. The "click" when the relay turns on and off is barely audible (the project box muffles it well). I already had an aqua lifter pump, tubing, and a container, and the whole thing was up and running in about an hour. Great purchase, highly recommend this item.
  • Fun for a DIYer By on 8/15/2017

    This kit is fun to out together for a DIYer. It works great and I see no reason that it will not last many years.
  • Long Term Update By on 6/27/2016

    Been using this ATO with aqua lifter pump for 4 years now with absolutely no issues. was fun to wire up as a DIY'er with straightforward instructions. I also purchased an additional kit for shutting down my return pump if my display is overfilling. That kit has also worked flawlessly... Also highly recommend the aqua lifter pump... I've ran my reservoir dry on a number of occasions and the pump is still going strong. Thanks BRS!
  • Has worked flawlessly 1 year By on 1/20/2016

    This kit was easy/fun to build. It's been in use for about 1 year and has worked flawlessly. I just bought another one for my new 110 gallon project. Thanks BRS!!
  • Just what I needed! By 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 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 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.
  • Good product By on 6/10/2015

    So far so good. I've had this running for a little over a month now with no issue's.. vary good product for the money
  • Awesome ATO! By on 12/21/2014

    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 on 10/27/2014

    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
