ReefATO+ Auto Top Off System

Reliable Auto Top Off System Built-in Temperature Monitor Leak Detector Included ReefBeat App Connected Not Just for Red Sea Aquariums*   Water Level Sensor Ultra Reliable. The ReefATO+ sensor features a built-in backup sensor 1" above the primary sensors to automatically shut down the ATO pump in the event of an overfill. With multiple probes built onto the sensor, an indication of actual water level can always be seen on the ReefBeat App.   Temperature Monitoring 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. If 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.
