3 Reviews "Smart ATO Automatic Top Off System"

Small but Powerful
Gus December 26, 2013 I admit that when I first set it up that it would not pass my standards and I would end up returning it or selling it. I have had years of problem free operation from my osmolator but am a bit of a tech nerd and had to have the smart ato after seeing it at Macna. It took all of 5 min to set up. The DC pump provides a good amount of flow and the sensor is truly responsive to the water level I set within my sump. Went through every imaginable test that I could think murphy's law would throw at it and the AFS technology safety function worked as promised.
Simply the best ATO out there!!!!
Peter L. December 26, 2013 I have only had this Smart ATO for a week but I must say this is a complete upgrade from the float style switches that I was using before. One unit replaced three float switches and what seemed like a ton of wires. Two thumbs up to AutoAqua for such a great ATO.
Super Simple
Casey C. December 26, 2013 I could not believe how easy it was to install. Took longer to read the instructions and pull the components from the box than to install the unit itself. I highly recommend this ingenious ATO.
