    The Smart & Reliable 3-in-1 ReefATO+

    The ReefATO+ is an exceptionally reliable auto top off system that is designed to maintain a stable salinity and water volume in a reef aquarium by automatically replenishing the water lost due to evaporation. In addition, the ReefATO+ provides two other critical aquarium health indicators: a fully featured on-line digital temperature monitor and an external leak detector. The 3-in-1 ReefATO+ auto top off system is not just for Red Sea Aquariums, it can be used on any brand aquarium system.

    • Ultra Reliable Auto Top Off System
    • Built-in Titanium Temperature Monitor
    • External Leak Detector
    • ReefBeat App Connected Controller
    • Upgrade Kit for Red Sea Aquariums

    If you don't own a Red Sea Reefer Aquarium, check out the ReefATO+ instead which includes the magnetic corner bracket needed to mount the probe.

    Water Level Sensor

    The EC technology titanium probes detect the water level that triggers the pump to be switched on and off to maintain a stable water level and salinity.

    Fail-proof (solid-state EC technology) water level sensor, with built-in back-up pump-OFF probes located 1” above the normal pump-OFF point.

    The full array of the Reef-Spec titanium probes gives an indication at all times of the actual water level relative to the sensor, which can be seen on the ReefBeat App at all times.

    Temperature Sensor

    The temperature sensor integrated in the ATO+ sensor has been pre-calibrated to give an accuracy of ±0.1°.

    The ReefBeat App allows you to set a narrow “desired” temperature range, and a slightly wider “acceptable” range, that will be seen on-line in the ReefBeat App and in the full temperature logs. In the event that the temperature goes outside the acceptable range you will get a notification to your smartphone.

    The detailed logs will show you the minimum, maximum and average temperatures at 15 minute intervals for the past 28 days.

    ATO Pump

    • Quiet, variable flow, 12 vdc ATO pump.
    • Cylindrical design with diameter of 4.5cm / 1.8” to fit inside standard jerrycans.
    • Max flow rate 300 lph / 75 gph, Max head 2.5m / 8’, power 6–10W.
    • Pump performance monitor in the controller will shut down the pump automatically and let you know through the ReefBeat App if it is not connected, stalls or RO reservoir runs dry.
    • Pump speed is automatically adjusted according to your installation to maintain a flow rate of approximately 72 lph / 18 gph ensuring a splash proof and quiet flow of water into the sump.
    • The noise damping rubber impellor chamber cover and impellor can be removed for pump maintenance.
    • Includes lock-nut on the outlet hose barb for secure connection to the silicon tubing.

    Leak Detection

    The highly sensitive, Reef-Spec leak detector with saltwater resistant titanium probes detects the full range of waters from RODI to seawater.

    If a leak is detected the ATO Auto-fill is immediately disabled, and after a few seconds to confirm that the leak persists, the controller sounds an optional audible alarm and sends a notification to your mobile device.

    Connect the Leak Detector to the Emergency Quick-action for the aquarium and ReefBeat eco-system will automatically shut down other ReefBeat devices such as the ReefRun return pumps.


    l-proof (solid-state EC technology) water level sensor with built-in safety shutoff.

    Automatic shut-down if the sensor is not connected, if the pump runs significantly longer than normal, if the RO reservoir runs out of water or if a leak is detected.
