The AutoAqua Smart ATO Nano G2 delivers reliable, precise automatic top-off performance in an ultra-compact design, built specifically for nano and pico aquariums. Maintaining stable salinity is critical in smaller aquariums where evaporation can quickly affect water parameters. The Smart ATO Nano G2 automatically replenishes evaporated water to help maintain a consistent water level.
The Smart ATO Nano G2 combines an optical dual-sensor and diaphragm pump into a single compact Hang-On-Back (HOB) unit for a clean, streamlined installation. Designed for both saltwater and freshwater aquariums up to 50 gallons, it features a quick plug-and-play setup with an adjustable mounting system compatible with both rimmed and rimless aquariums.
The upgraded G2 dual optical sensor provides highly accurate water-level detection, capable of sensing changes as small as 0.3 mm. The intelligent sensor design helps minimize false readings caused by water droplets or buildup, while the integrated failsafe sensor prevents overfilling in the event of a primary sensor issue.
The Smart ATO Nano G2 features AutoAqua’s Quick Security Technology (QST), an intelligent safety system that continuously monitors its operation and automatically shuts itself down if abnormal conditions are detected. This protects against overfilling, dry running, and pump damage while providing dependable long-term performance.
Designed with simplicity in mind, the Smart ATO Nano G2 features tool-free installation and integrated cable management to reduce clutter around the aquarium. Its compact footprint makes it ideal for nano tanks, all-in-one aquariums, and tight cabinet spaces.
