The Red Sea ReefATO+ System is a highly advanced 3-in-1 automated top-off system designed to provide total stability and safety for marine reef aquariums. Operated via Wi-Fi through Red Sea’s ReefBeat app, this system combines fail-proof water level management, an online digital thermometer, and an ultra-sensitive leak detection grid. It serves as a comprehensive ecosystem monitor that actively prevents accidental salinity drops, dry-running pumps, and destructive water damage.

Solid-State Level Sensing: Ditching failure-prone mechanical float valves and optical eyes that get clouded by salt creep or snails, the sensor features high-grade titanium probes using EC technology. If the water drops below the "pump-on" probe, the system triggers a fill until it touches the "pump-off" probe.
-
Triple-Tier Hardware Safeties: In the event of an overfill, a physical backup probe sits exactly 2.5cm (1”) above the normal shut-off point to instantly cut power. Additionally, the micro-processor tracks average run times to enforce a built-in automated pump timeout, and monitors power consumption to immediately disable the system if the pump stalls or runs dry.
-
Integrated Reef-Spec Thermometer: Built directly into the lower titanium probe assembly is a pre-calibrated temperature sensor accurate to ±0.1°C. It records real-time updates directly to the app home page every 60 seconds and logs detailed minimum, maximum, and average history charts over a rolling 28-day cycle.
-
RO/DI & Saltwater Leak Detection: The independent, titanium-probe leak pad detects everything from zero-TDS RODI water to dense saltwater. If a leak crosses the grid, the controller stops the top-off pump instantly, pushes emergency push alerts to your smartphone, triggers an audible alarm, and activates global "Quick-Actions" to automatically shut down paired devices like ReefRun return pumps.
-
Complete Professional Install Kit: Out of the box, the system includes a 3-meter thick-walled silicone line (5mm ID), a dedicated click-on tube holder, and a critical mechanical siphon breaker to stop accidental, gravity-fed line back-siphoning into your sump.
