When levels dip below the set point, the pump activates and refills until the upper limit is reached. A dedicated reservoir probe adds a safety layer, triggering alerts if water becomes unexpectedly low and automatically halting the pump if it risks running dry.\u003c\/p\u003e\n\u003ch2\u003eSetup \u0026amp; Compatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned for ease of use, the unit installs on tank glass up to 3\/8 inch thick and ships with all essential components. The low-profile pump and flexible hose manage refill without kinking or leaks, and the system supports water movement from a bucket to the tank with a practical height head. The integrated controls also let you monitor temperature and adjust readings in Fahrenheit or Celsius, adding a layer of convenience for mixed-species environments.\u003c\/p\u003e\n\u003ch2\u003eWhat You Get\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eReliable ATO system with magnetic glass mounting\u003c\/li\u003e\n  \u003cli\u003eMini DC pump and soft hose for flexible installation\u003c\/li\u003e\n  \u003cli\u003eTop-off sensor, reservoir probe, and audible alert for safety\u003c\/li\u003e\n  \u003cli\u003eTemperature display with unit conversion and manual refill mode\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: This device is designed to assist with water level stability and should be used as part of a broader aquarium maintenance routine.
