Our smart ATO 360P uses AFT to identify and recognize any false water fluctuation; It only starts the pumps when the level is truly low. Extended Time Filling Technology ETFT is Fzone own patented algorithm. During the initialization process the controller recognizes the tank size by timing how long it takes to fill the water from "Low" to "High" position; That time is called ETFT(Extended Time Filling Time). In normal refilling, the ATO fills the water to the LOW position and continue pumping for a circle until the water level reaches about "LOW" but never goes above "High". Precisely keep the water between the LOW and the High sensor positions. This unique feature allows extra time of rest between refills, can substantially increase the products's life span. Review: Great ATO that was easy to install - Great product with useful features. Easy to install and works very well. The low resovior water warning light is a great touch. Review: Great value ATO - Bought this a few months ago and thought it was time for a review. Nice small optical ATO that has proven to be very reliable on a small nano reef tank. Easy to setup and and absolutely trust worthy. Snall pump is pumping RO water about 1 metre up with ease. Overall, a great value and trustworthy piece of kit! ## Features - Upgraded 2.0 ATO System：The 2.0 ATO system ensures efficient daily water level maintenance for saltwater and freshwater tanks, making it ideal for use during trips or holidays. The upgraded interface allows you to easily start, pause, or resume the system with the FZ button - Compact and Versatile Design：The optical sensor measures just 0.79 inches in diameter, making it suitable for rimmed, rimless, or sump tanks. Dual sensors, spaced 0.1 cm apart, monitor water levels with precision, maintaining a difference of only 0.6 cm. Recommended for tanks with wave fluctuations under 1 cm. - Enhanced Safety Features：QST 2.0 technology provides real-time overfill protection. The system stops the pump and triggers an alarm if refilling exceeds six times the preset limit. It also detects sensor issues and low reservoir levels for added safety. - Quiet Micro Pump：The compact pump fits tanks with neck sizes over 1.97 inches, offering a flow rate of 74 gallons per hour and a lift height of up to 2 meters.
