This ultra-reliable automatic top-up system includes a highly accurate temperature sensor, an external leak detector, and a smart controller that connects it to the ReefBeat ecosystem.

The ReefATO+ is equipped with a one-piece water level sensor and a titanium sensor array that determines whether the water level is above, below, or at the desired level. It also features a quiet, microprocessor-controlled pump with multiple safety features, including an automatic shut-off if the pump runs for too long or dries out.

Each fill is performed within a precise 3 mm range, ensuring your system's water volume and salinity remain at the correct and stable level. Furthermore, the maximum level backup probes only activate when the ATO pump is running, so common level fluctuations, such as those caused by using roller filters or your return pump shutting down, won't trigger false alarms. The water level probe also includes a precise digital thermometer, pre-calibrated to 0.1 degrees, which generates a complete history and high/low temperature notifications.

The ReefATO+ also includes a highly sensitive Reef-Spec leak detector. It will send you a notification and even shut off pumps connected to ReefBeat if a freshwater or saltwater leak is detected.

The ReefATO+ is part of the ReefBeat ecosystem, so it has many smart features such as disabling automatic top-up during maintenance work and water changes, or stopping your ReefRun pumps if a leak is detected.

Current REEFER Red Sea owners can purchase a ReefATO+ upgrade kit (at a discounted price) to replace the float valve system.
