The Smart AWC Duo is the latest version of the fully automated compact water change unit from Autoaqua. It uses two uniquely designed duel level optical sensors that are suitable for both aquariums big and small. Simply mount the two sensors on your tank, adjust their heights with the magnetic mounts and program the desired auto water change settings using the touch screen. Waterchanges can be performed automatically at a desired set frequency or performed manually at the press of a button. This can allow regular small waterchanges to be performed daily or even muliple times a day with little to no effort.
Integrated with QST (Quick Security Technology) the Smart AWC provides real-time fail safe protection against failure along with built in failsafe sensors.
The unit also includes an ATO function to replace water lost through evaporation between water changes.
