Product Description


    Automate freshwater replenishment, and say farewell to heavy lifting, unstable water parameters, and the need to frequently watch your water line.

    Topping off evaporated water for our aquariums is a tedious but essential task that every hobbyist encounters to maintain stable specific gravity & salinity levels.

    The HydroFill Ti ATO Controller takes advantage of your water's conductive properties to complete a low voltage circuit and cause a control relay to actuate and replenish water as it evaporates. This departure from outdated float sensors, offers the latest automation in electronic sensing for precise accuracy, repeatability, and no-moving part reliability.

    Customize your own "High and Low" set points to prevent constant On/Off cycling prone to single sensor design.

    Sensors utilize rare earth neodymium magnets for stationary placement and simple out of the box installation. Small form factor makes it the ideal choice for nano to full size aquariums. Two Titanium electrodes are housed in each sensor for redundancy & consistent long-term performance in harsh marine environments.

    1. Whole Tank Killed Off Review by BenK

      I installed this about 9 months ago and worked great out of the box. However recently I was away and it went to top up and never switched off again so dumped about 20 gallons of RO water into my tank. This caused a huge flood and diluted the salt level too much. I have lost everything including a large carpet anemone I have had for over 20 years. Not safe to use this ATO. It is going in the garbage.
      Now I have to start from scratch with my tank again. (Posted on 6/24/2019)

    2. so far very pleased Review by .....

      I have never owned an ato before, and it is still new however I'm very impressed so far. Excellent investment (Posted on 4/5/2018)

    3. Like it Review by Ato

      Well I had a Colour marine ato that all of a sudden over filled and set off the second trigger... so I picked up this one and the matching pump. The pump is silent and fairly quick. The only downside is there is no alarm for the reservoir tank.. and it does not come with hose to plumb it.. this is not a huge deal but if your half hour out of town and expecting to hook it up right away you will need to get hose.... all and all it seems to work great.
