The Hydrofill Titanium takes advantage of waters conductive properties allowing it to monitor the water level in your aquarium. Two titanium sensors allow you to set your own custom high/low set points preventing cycling like many single sensor top off units. Having the ability to customize the high and low set points makes the Hydrofill Titanium great for almost any size tank or sump.

  • Best thing I’ve added this year By Richard on 10/22/2017

    This ATO is awesome it is the best product I’ve add this year
  • Excellent and reliable By cdavmd on 9/14/2017

    I've had it for about three years. Works perfectly. The suction cups eventually gave out but the magnets have worked without issue, expansion or corrosion. The sensors have needed algae scraping a couple times when I have neglected them and the ATO did not refill as expected. Once cleaned it works perfectly again. The pump that is sold separately works nicely but is somewhat large and bulky. Overall it is reliable and works as advertised.
  • Best technology on the market By (Murphys Reefing) on YouTube on 7/2/2017

    I've been running for a year, only issue I've had is if some slime coats the probe.. NO biggie.. I've been using similar technology at work for the last 10 years and the probes haven't failed yet. Should be same results here, just depends on the mother board
  • Good and small By Dan on 5/30/2017

    I have had this on my tank for 18 months. It works very well. I have never had a problem with it. I clean the probes from time to time but they never seem to have any buildup on them. My favorite part about it is how easy it is to adjust the probes height with the magnets whenever I need to, and they are very small and do not take up a lot of room in the back of my BioCube.
  • WOW!!! By Thomas on 5/23/2017

    I had been using the Tunze Osmolator ATO, for the past 3 years, and could not maintain a proper level. Have been using this system, for the last month, and the level never strays above or below the set level probes. Highly Recommend this ATO.
  • Great ATO By Radster on 10/12/2016

    100% Satisfaction. Been using for about a year now. Adjust your own water level trigger to any depth. Super affordable option vs. other OVERpriced ATOs that do the exact same thing and are unpleasant to the view. Compatible with any pump. tube it up and you're set.

Product Questions

Is there a recommended pump for this system?
Question by: Brian on Jul 12, 2016 2:39:00 PM
Hi Brian,
You can use almost any pump that suits your ATO needs like the Aqua Lifter, BRS 50mL doser or any utility pump, however we would recommend matching the Hydrofill Titanium ATO controller with the Titanium HydroFill ATO Pump.
Answer by: Charlie (Admin) on Jul 13, 2016 7:12:00 AM
Hi. What happens if the upper sensor fails for some reason? Will it just keep trying to fill?
Question by: Jeff on Jun 5, 2017 10:17:00 PM
This ATO system does not have a timeout feature, so there is a potential failure point, however each probe array for high and low water level actually has two sensors on it for redundancy, so this does lessen that risk.

Happy reefing!

What's the difference between the titanium model and the previous version?
Question by: Geoff on May 12, 2016 1:44:00 PM
Great question!
The New titanium will use more affordable titanium designed probes which are easier to manufacturer. The design and performance will be the same between the units.
