Making Water Changes Simple and Smart

Simple to install and includes everything needed to operate the AWC with ATO function. Smart AWC Duo’s two patented optical dual sensors and a touch screen can perform a water change and water top off with ease.

A New Experience

The intuitive touch screen interface saves you from complicated settings and allows you to complete multiple tasks effortlessly. You can use the Smart AWC Duo with saltwater or freshwater applications and on aquariums of all sizes. This smart device makes water changes effortless.

Precise Detection with Double the Protection

The Smart AWC Duo has two patented optical dual sensors, so if the primary sensor is defective, the failsafe sensor will take over and prevent over ?lling or over-drain water from the aquarium. The easy-to-install magnetic dual optical sensors can detect the water level precisely and ensure an accurate water change and ?lling volume.

Integrated with Safety Technology

The unique Quick Security Technology (QST) protects the aquarium by spotting potential failure situations to prevent any disaster. The built-in audible alarm will alert you within seconds of an accident.
