Quick Overview

Innovative Marine's HydroFill ATO Controller System uses electronic sensing through water's conductive properties to complete a low voltage circuit and cause a control relay to alert the controller to turn on your pump and replenish the tank's water. No more outdated float sensors or moving parts that can fail. Place the sensors at your "High" and "Low" set points to prevent constant on/off cycling prone to single sensor design.

Can I just buy the pump? The controller is fine.

Full Details

Auto Top Off systems have been around for a while to help reef hobbyists automate the chore of topping off your system's water and maintain stable gravity and salinity levels. Auqa Gadget HydroFill ATO Controller system uses sensors attached with rare earth neodymium magnets for simple stationary placement. Small form factor makes it ideal choice for nano tanks but will perform for full size aquariums as well.

Place sensor on your tank for your high and low points of your water line. Sensor contain two chemically inert graphite electrodes for redundancy & consistent long-term performance in harsh marine environments as well as freshwater environments. Through sensing or not sensing the conductivity of the water, the sensors alert the controller to start or stop which prevents the on/off cycling common with single sensors.

  • Don't buy By Raymond on 4/28/2016

    Doesn't work half the time. Will flood your house.
  • Not good By Donnie on 3/23/2016

    Fails all the time. Over fills the water level causing skimmer to dump back into sumo. Worst thing I have purchased for my tank.
  • FULL SYSTEM? By Ron on 2/17/2016

    This is sold as a full system but it doesn't even have a pump. Cost with a pump is over $300 Not worth it!
  • Not Any Good By vinci666 on 2/12/2016

    Failed within 2 months, I strongly urge you to look elsewhere
  • Look elsewhere By Big B on 12/22/2015

    Failure across the board. The unit is never functioning properly.
  • Product Sucks By Flooded Living Room on 12/7/2015

    Worked for about 2 months perfectly. Flooded my living room 3 times and messed up my wood floors. Any little thing affects the sensors. Tried cleaning them several times works for a day or so then back to square 1. Bad purchase looking for new ATO now. One good thing i have to say is that the pump is awesome.
  • Poor System...fair service By Sam on 7/16/2015

    Had the same issues with sensors not working...the entire system was replaced by the company and has been working for about four the last week it has overfilled my sump twice...I would not recommend this product at all...a total waste of money.
  • Very Poor By Martin on 7/13/2015

    This was bad for me from the start. If you get foam or dirt on the sensors it does not work. Has flooded my living room several times. Do not purchase!
  • Failed within 1 week By Patrick on 4/28/2015

    Poorly designed and over priced
  • Not bad By Thegoz007 on 4/1/2015

    This is a good pump. I like the rubber hose that I can just drop in. I use 7 gallon water containers I got from Wal-Mart for my ato and after removing the valve this hose fits perfectly. It does make a little noise out side of that no problems. It does fill fast, so it does fill higher than needed and made my ATO alarm go off. However I don't mind it as I really like the pump. Easy assembly, and attached to the side of the tank with ease.
  • the second one works the best By Russell on 3/29/2015

    the first one I got did not work at all, and looked like it was used as a display or something, sent it back to get fixed, they sent it back as repaired re installed it as it is a no brainer to install must be in as calm area as to much water movement can mess it up, it is not like the video they show,

    ok still had problems with it, so I sent it back again and they sent me a new one

    it has worked ever since
    , but just like every thing you still have to keep an eye on things...

    I DO LIKE IT but at first it drove me NUTS
  • no good By Caution on 12/10/2014

    I've purchased two these. First one lasted about 3 1/2 months. bought a second one thinking it was a fluke, but I was disappointed when the second lasted less than 6 months. DO NOT BUY!!!!!
