Innovative and Smart ATO for Nano Aquariums
The Smart ATO Nano Kit is a plug-and-play auto top-off system made by Autoaqua. Specifically designed for nano and pico aquariums under 50 gallons, this ATO nano kit will automatically monitor and refill evaporated water in small tanks. It will also help keep a stable osmotic balance for saltwater applications, which is particularly important for small tanks that are sensitive to continuous salt concentration fluctuations.
The Smart ATO Nano is beautifully crafted to allow simple installation and silent operation. A strong diaphragm pump and a dual optical sensor are combined in one pack, avoiding an unwanted nest of wires.
Integrated With Quick Security Technology (QST)
Smart ATO Nano uses QST for real-time protection against product malfunctions such as overflowing or an empty reservoir resulting in the pump running dry. In addition, the system’s controller will give a visual alert the minute it detects unusual behavior for a device.
