Intelligent Redundancy:

  • Frequency Alert: The system will beep to notify you that your aquarium has not been topped off for an unusual amount of time, at least 24 hours, and double the average time between Top Off. Ex: if the Avg. time between topping off is 12 hours, the system will notify you after 24 hours of not topping off.
  • Overfill Alert: The system develops and average time that the pump is running each time the system is activated. If the system detects that liquid has been dispensed for more than 3x that average baseline time, it will shut the pump off and create an audible alarm.
  • Empty Reservoir Alert: The system can detect when the top off pump is drawing excess air/running dry and automatically shut the pump off and create an audible alarm.
  • Sensor Obstruction Alert: The system will detect if the in-tank sensor needs to be cleaned, is being obstructed or is out of alignment. This is denoted by a flashing blue light.
