JBJ Nano ATO – Advanced Kit Overview for Automatic Top-Off Control

The JBJ Nano ATO – Advanced Kit makes aquarium water level management feel like a walk in the park. Whether you're a seasoned reefer or just dipping your toes into the salty world of aquatics, this auto top-off system takes the guesswork (and salt creep) out of topping off evaporated water.

Let’s be honest—constantly adding water to your tank manually? It’s about as fun as watching paint dry. Thankfully, JBJ’s Nano ATO is here to save your tank... and your sanity.

Why Choose the JBJ Nano ATO?

Think of this kit as your tank’s personal assistant—quiet, precise, and totally on top of things.

  • Protective Optical Sensor Cover
    Keeps curious critters (yes, that clownfish) from messing with the sensor. Also blocks light to reduce false readings.

  • Fully Waterproof Sensor
    Mount it anywhere without worrying. It’s as waterproof as your favorite pool floatie—only more useful.

  • Strong Magnetic Mount
    No tools needed. It grips glass up to 15 mm thick tighter than your cat clings to your hoodie.

How to Install Nano ATO in Just a Few Steps

You don’t need an engineering degree to install this. Just follow these quick steps and you’re golden:

  1. Mount the sensor just below your desired water level.

  2. Place the DC pump inside your top-off reservoir.

  3. Use the guide rail to clip the tube neatly into the aquarium.

  4. Plug in the power supply first, then the pump.

  5. Let the system auto-fill until it reaches the set level—like magic, but real.
