MagTool ATO-360P Smart Aquarium Auto Top Off Pump

Smart, Precise Water Level Control for Your Aquarium

The MagTool AUTO TOP Off (ATO) ATO-360P is a smart aquarium water refill system designed to keep your tank's water level stable with minimal intervention. Using dual optical sensors and advanced control algorithms, it refills evaporated water automatically, helping you maintain consistent conditions in both freshwater and marine aquariums. This reduces salinity swings, protects equipment, and supports a healthier environment for fish and corals.

The compact optical sensor unit measures only 0.8 inches in diameter and works on rimmed, rimless, and sump tanks. Dual precision sensors, positioned just 0.1 cm apart, monitor water level changes with high accuracy, keeping fluctuations under approximately 0.6 cm. The system includes a controller with integrated ETFT (Extra Time Filling Technology), AFT (Anti-Fluctuation Technology), and QST 2.0 (Quick Security Technology) for safe, efficient operation. ETFT learns how long your tank takes to refill between the LOW and HIGH sensor positions and calculates an extended filling time to maintain a stable level. AFT filters out false level changes from waves or turbulence, so the pump only activates when the water truly drops below the LOW point. QST 2.0 continuously monitors filling time, stopping the pump and triggering a visual alarm if the refill takes more than six times longer than expected, helping to prevent overfilling, dry running, or flooding.

The ATO-360P set includes everything needed for installation: controller, dual optical sensor assembly with strong magnet mount (supports glass up to 20 mm thick), submersible pump rated at approximately 74 gph (280 lph) with a maximum head of about 8.2 feet (2.5 m), check valve to prevent backflow, hose holder for secure tubing placement, and power adapter (AC 100-240V, 50-60 Hz input, DC 12V/1A output). Cable lengths are designed for flexible mounting: approximately 6 ft (180 cm) power cable and 4 ft (120 cm) between sensor and controller. Built-in LED indicators clearly show operating status: alternating red/blue during initialization, solid blue on standby, slow blue flash during refilling, rapid blue flash when the HIGH sensor is reached, and red flashing for QST 2.0 alarms. By automating top-offs, the MagTool ATO-360P helps avoid issues caused by evaporation, such as scale formation, heater exposure, and gradual deterioration of water quality.

Why It's a Smart Choice

• Maintains a consistent water level to support stable salinity and water parameters in freshwater and marine systems.
• Reduces manual top-off work, saving time and simplifying aquarium maintenance, especially during travel or busy periods.
• Advanced ETFT, AFT, and QST 2.0 protections help prevent overfilling, pump damage, and flooding for safer long-term operation.

FAQ

Q: Is the MagTool ATO-360P suitable for both freshwater and saltwater aquariums? A: Yes. It is designed for all sizes of freshwater and marine tanks, including sumps, where stable water level and salinity are important.

Q: How does the system prevent overfilling and flooding? A: The dual optical sensors define LOW and HIGH water levels. ETFT calculates safe filling time, AFT ignores minor wave-induced fluctuations, and QST 2.0 stops the pump and triggers an alarm if refilling takes abnormally long.

Q: What glass thickness can the magnet mount handle? A: The included magnet mount is engineered for aquarium glass up to approximately 20 mm thick, allowing secure placement on a wide range of tank types.

Q: Do I need any extra parts to install it? A: The package includes the controller, sensors, pump, magnet mount, check valve, hose holder, and power adapter. In most setups, you only need your reservoir and suitable tubing routing to start using the system.

Q: Will it work if my tank has surface movement from wavemakers or filters? A: Yes. The Anti-Fluctuation Technology (AFT) distinguishes real water level drops from short-term surface movement, so the pump does not cycle on and off unnecessarily.
