Why Choose Duetto ATO ?
With huge features jammed in a tiny package, the Duetto is the perfect ATO for your aquarium. XPAqua’s proprietary dual-optical sensor packs two precise level sensors in one incredibly small package. In addition to keeping your water level constant, the two sensors also work in concert with the intelligent QST programming to help prevent overfilling.
All the installation parts are included and a magnetic coupling allows you to easily mount or adjust the dual-sensor. Installation takes just seconds so you can spend less time working on your aquarium and spend more time enjoying your aquarium.
