The AutoAqua Smart ATO Micro is the smallest auto top-off system available today. This makes it especially great for nano aquariums that don’t have a lot of extra space inside the tank.
How small is it? The level sensor is about the same diameter as a penny! If you install the sensor in your Nano tank, you’ll never notice it’s there. The magnetic mounting system is tiny but works on glass, plastic and painted surfaces up to ½" thick. The optical sensor has no moving parts. No float switches. Nothing to get stuck. The sensor can be mounted in a sump or directly in the aquarium.
Installation is quick and easy; no programming or adjustments are needed. Simply place the water level sensor at the desired water height in the sump or aquarium. As the water evaporates the sensor will turn on the DC water pump in your freshwater reservoir. You can use a bucket or an aquarium to hold the make-up water. When the pump refills the aquarium to the desired height, the Smart Mini Controller shuts off the pump.
AutoAqua incorporated their QST (Quick Security Technology) into the ATO’s monitoring system. The Smart Mini Controller records the time it takes to top off the aquarium the first time you turn it on. If at any time the refill pump runs longer than three times the initial top off time, the system sends out an audible alert and turns on a blinking red LED. The refill pump also includes a siphon breaker to prevent backflow into the reservoir.
What we really like about the Smart ATO Micro system:
Very tiny sensor – ideal for small marine and freshwater aquariums
Kit contains everything needed right out of the box – refill pump, 6.5’ hose, sensor, power adapter and magnetic mounts for the sensor and refill tubing
Red LED and audible warning alert and blue LED for normal operation
Easy set-up
Water level memory can be reset if necessary
Quiet operation

Q
Will this work for 40 gallon innovative marine tank?
This thing is tiny. About the size of a nickel. I set mine up in less than 5 min and it has worked perfectly for me in my IM 20. I wish the magnet was a little stronger but it’s not a huge deal. I pump 4’ vertical with it. My hydra 26’s do not effect the sensor at all.
PROS
small, reliable, easy to set up, works with large and small tanks
CONS
optical sensor is subject to fouling
REVIEW
This item has been working flawlessly in my 75g tank for 3 months now. I love it. It's wise to clean the sensor occasionally. Well worth the money and easy to install (5 min).
Have had this working on various tanks since 2016 without issue. Easy to hook up and this thing is super tiny! It can work for large tanks down to the tiniest picos.
CONS
They could have thrown in some Velcro ties for cable management.
REVIEW
Simple piece of equipment that works as expected. Doesn't have 47 redundancy sensors like some other ATO's have. That was not a problem for me, as I didn't want the back of my All-In-One looking like an EDM festival in middle of the night. Set up was simple and the equipment was operational in less ...Read More
