Overview

The Auto Aqua Smart ATO Duo is an automatic top-off system with dual sensor redundancy, designed to keep your tank's water level topped up consistently without manual daily top-ups.

Evaporation causes salinity to creep up between top-ups if done manually, and an ATO with dual sensors gives extra protection against a single sensor failure causing an overflow or dry-run situation.

Key features

Dual sensor design for added reliability and safety
Automates daily top-up of evaporated water
Helps maintain consistent salinity by preventing evaporation-driven drift

Who it's for

Reef and marine tanks of any size wanting reliable, automated top-up with a safety margin against sensor failure.

Setup & tips

Position sensors according to the manufacturer's guidance to avoid false triggers from surface agitation
Check the reservoir regularly so it doesn't run dry unexpectedly
Test the shut-off function periodically to confirm both sensors are working correctly
