Topping off evaporated water is only half the maintenance equation - routine partial water changes are the other half, and AutoAqua's AWC line automates both from a single system.
Why Automate Water Changes, Not Just Top-Offs
A standard ATO only replaces evaporated freshwater, leaving the actual routine water change - draining old water and adding fresh saltwater - as a manual task. The AWC line automates both jobs together, using dual optical sensors and quiet operation.
Choosing a Model
- AWC Auto Water Change Duo - automates both top-offs and routine partial water changes in one system, using dual optical sensors and quiet DC-controllable pumps.
- AWC Auto Water Change Lite - combines top-off and water-change functions in a more compact system, rated for tanks up to 150 gallons.
Setup Tips
- Size to your tank volume - the Lite covers tanks up to 150 gallons, while the Duo suits larger or more demanding setups.
- Pre-mix and stage new saltwater in the system's reservoir on a schedule that matches your water change routine.
- Monitor the first several cycles closely to confirm the system is performing water changes as expected before fully trusting it unattended.
