AutoAqua Smart ATO Nano

The AutoAqua Smart ATO nano is a compact and easy-to-use auto top-off (ATO) system designed specifically for nano and pico aquariums under 189 Litres.

The ATO nano uses a diaphragm pump to automatically refill evaporated water, keeping your tank’s water level constant and preventing salinity fluctuations.

The ATO nano is a plug-and-play system that is simple to install.
Simply hang it on the back of your tank, connect the tubing, and plug it in.
The ATO nano will then automatically start monitoring the water level and refilling as needed.

The ATO nano features a number of innovative features that make it a great choice for nano and pico aquariums.

These features include:

• Quick Security Technology (QST):
  QST protects your tank from overfilling or running dry by automatically shutting down the pump if there is a problem.
• Dual optical sensor: 
  The dual optical sensor provides accurate and reliable water level monitoring.
• Replaceable diaphragm pump: 
  The diaphragm pump is easy to replace, so you can keep your ATO nano running smoothly for years to come.
• Prefilter and anti-siphon valve: 
  The prefilter removes particles from the reservoir, protecting the pump and preventing clogging.
  The anti-siphon valve stops waterflow due to forward siphon, preventing flooding.

Beautifully crafted and features a simple, one-piece design that makes it easy to install and maintain.
The perfect solution for busy aquarist who want to keep their nano or pico aquarium looking its best.
It is also a great choice for beginners who want an easy and reliable way to maintain their aquarium.
