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 No more outdated float sensors or moving parts that can fail.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.

Product Questions

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

Hey there,
The pump is sold separately with the power supply in the link below. Feel free to let us know if you have any further questions!

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.

  • Bad product By Jon on 9/17/2016

    Simply put, it fails. After working well for a few weeks, the pump mechanism failed. Now the sensor mechanism makes a loud clicking sound and doesn't accurately or consistently adjust when water level changes.
  • Garbage! By DiscusZ on 6/21/2016

    Waste of money sensors fail to easily, there is no fail safe it WILL flood your house, or put too much water in your sump
    I rate this a ZERO star
  • Complete GARBAGE!!! Dont waste your money!!!!!!! By Jim H on 5/28/2016

    If I could give 0 Stars I would this ATO is complete garbage! Does not detect when container is full 90% of the time.! Sent one back was told there was nothing wrong with it. Got it back it seemed to work during my week of testing, so I put it back on my ATO container, worked find for 3 weeks then it never shut off and dumped water on the floor! In the garbage it goes.!!!!!!!!! complete POS
  • 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
