The ReefATO+ has a solid-state water level sensor with an array of titanium probes that pinpoint if the water is above, below, or at the desired level. This comes together with a microprocessor-controlled extra-quiet pump and multiple safety features, including an auto-shutdown mechanism 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, such as when using roller filters or turning off the return pump, 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.
