About this item
- Upgraded 2.0 ATO System：The 2.0 ATO system ensures efficient daily water level maintenance for saltwater and freshwater tanks, making it well suited to 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 3 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. Optimized operation reduces unnecessary activations, extending pump life.
- Complete Accessories Included：The set includes strong magnets (compatible with tank walls up to 0.78 inches thick), a check valve to prevent backflow, and a 6-foot (180 cm) tube for quick installation.

More about this product
What upgrades have we made to ATO-580P?
Pause Button: Pause anytime for cleaning or maintenance, auto-resumes without resetting. Beeping Alarm: Flashing red light with beep alert for instant problem detection. One-Touch Initialization: Hold FZ button for 3 seconds to reset safely, no need to unplug. Light Positioning: Controller lights up while the sensor stays dark, reducing tank light pollution.
Dual Overflow Protection · Safer and More Reliable
High-Level Sensor Stop: Refilling automatically stops when the water reaches the high-level sensor. Quick Security Technology (QST): During initialization, QST sets a model-specific time limit. If refilling exceeds three times this limit, the system stops automatically to prevent overflow. Refilling Logic Upgrade All four ATO versions now feature upgraded refilling logic: refills stop at the high-level sensor instead of mid-level. This ensures more stable water levels, longer refill intervals, fewer pump cycles, less wear, and longer pump lifespan.
Wide Application · Fits Various Aquarium Setups
ATO is widely applicable for nano or large aquariums alike, ensuring stable water levels with ease. All freshwater and saltwater aquariums AIO tank sumps Bottom-filter sumps Freshwater display tanks Precise Optical Sensors AFT(Anti-fluctuation Technology) designed to accurately detect water fluctuations and prevent false refill triggers caused by pumps or wave makers. This ensures stable water levels, enhancing the efficiency and reliability of aquarium water management systems.
