About this item

  • Designed for RO/DI Systems: Our advanced ATO system seamlessly integrates with RO/DI setups, featuring a precision solenoid valve for automated water level management. It activates refilling when levels are low and stops once optimal levels are achieved, ensuring consistent water quality with minimal effort.
  • Dual High-Precision Optical Sensors: Outfitted with two sophisticated optical sensors for unmatched accuracy in water level detection. The primary sensor activates the refilling process when water levels fall, while the secondary sensor serves as a failsafe to prevent overflows, safeguarding your aquatic environment from potential hazards.
  • Patented QST3.0 Algorithm & AFT Technology: Features the exclusive QST3.0 algorithm, which intelligently ceases water addition if the target level is not reached within a predetermined period, effectively preventing overflow and enhancing system safety. Additionally, its AFT (Automatic Fluctuation Technology) accurately differentiates between water level fluctuations and actual drops, ensuring reliable operation.
  • Compact and Versatile Design: The LITE version boasts a slim profile at just 0.8 inches in diameter, making it suitable for any aquarium setup, including sump tanks, AIO sump configurations, and display aquariums. Its magnetic mounting system simplifies installation, offering a blend of functionality and visual appeal.
  • Comprehensive Kit with One-Year Warranty: Arrives ready to use with all necessary components, including sensors, solenoid valve, power supply, and 1.5 meters of PU tubing. Comes with a one-year warranty that covers sensors, the solenoid valve, and power supply, ensuring your investment is secure.

I love to hear this thing turn on and off!! Haha. It works perfectly and has kept my salinity stable for weeks now! This was a great purchase!

I wish it was made in USA. But if you’re looking for an easy way to top off your aquarium, this is for you. This is my second one. It lasted about 18 months. Probably would have lasted longer if I had cleaned it. But I didn’t.

it was really easy to set up and so far it seems to be working well. my water level looks good I tested it once after the initial set up. So far so good

Worked okay for 2 weeks then flooded my tank with RO water, over flowing the tank, onto the floor, and dangerously lowered the salinity in a matter of minutes. Major ordeal to cleanup and correct tank parameters in the middle of the night. This happened on the last day of the return windows, go figure.

Im probably about two months into use on this guy on an IM 15Gallon. I have had no issues, its accurate and has functioned without any flaws at all. Time will tell on longevity.

Got the ATO-LITE for my 15 gallon AIO reef tank. Its placed in the return pump section. Its really good and cuts off pretty quickly once it hits the overflow sensor. Its nice for the price that it comes with a magnet too. I just don't see the need for anything more than this. Gets the job done.

This ATO was insanely easy to install and the return pump is powerful for how small it is. I am very fond of the safety measurements put in place my the ATO resulting in no tank overflows or tank water flowing backwards into the RODI container.
