Equipped with optical level The blue optical level sensor is used to monitor the water level to determine whether the water needs to be refilled, and the red optical level sensor is used to prevent overflow of refilled water. The ATO One 2 SE contains a wealth of status indicators for when the refill is overflowing or time-out. Submersible pumps The ATO One 2 SE has an indicator light and buzzer to alert when the pump is not plugged in or when the refill bucket is out of water. ## Features - Kamoer's new upgraded ATO one 2 se automatic water refill is a great addition to your home fish tank!
