The ReefATO+ is an exceptionally reliable auto top-off system + accurate temperature monitor + external leak detector, and it comes with a smart controller that connects it to the ReefBeat eco-system.

The ReefATO+ has a solid-state water level sensor with titanium probes that pinpoint if the water is above, below, or at the desired level. It also comes with a microprocessor-controlled quiet pump that fits a 4.5cm / 1.8” diameter opening and has multiple safety features, including auto-shutdown if the pump is running for too long or running dry.

Each fill is completed within a precise 3mm band, keeping the water volume and salinity nice & stable. In addition, the higher-level backup probes only react when the ATO pump is on, so routine water fluctuations will not trigger any false alarms.

The water level sensor also includes an accurate digital thermometer that has been pre-calibrated to 0.1 degrees, which provides a full log and high/low-temperature notifications.

The ReefATO+ also includes a highly sensitive, Reef-Spec leak detector that will send you a notification and even switch off ReefBeat connected pumps if an RO or seawater leak is detected.

The ReefATO+ is part of the ReefBeat ecosystem, so it has lots of smart features such as disabling the auto-fill during maintenance work and water changes or switching off your ReefRun pumps if a leak is detected.

If you have a Red Sea REEFER G2 Aquarium or a Red Sea Reefer Peninsula Aquarium we offer the ReefATO+ as an upgrade kit which is supplied without the corner magnetic probe holder. Instead, the old style float valve can be unscrewed and the digital probe mounted in its place. The ReefATO+ upgrade kit is available here
