I have the AutoAqua Smart ATO Micro for my nano. This one has one sensor and it has been pretty solid for the last 2 years. The pump is quiet too. The only problem is that if the sensor gets covered in algae, it will malfunction. But if it stays relatively clean, then it shouldn't give you any problems. The Tunze pumps for the ATO are super loud, at least in my experience.

$8 float switch with hanger from eBay, $15 Toms aqua lifter, 5 gallon jug and done. Same type of set up over 10 years never a problem.

Algae will be an issue due to light spilling in my AIO

Tunze Osmolator 3155. It just plain works and works well. Don't get the nano version as it's just the float switch. The 3155 has optical sensor and back up float switch for emergency shut off. If the sump level gets too high it just sends off an alarm sound but will continue to work as soon as the water level goes back to normal. This can easily happen when the return pump or skimmer is temporarily shut off. I really don't like that some ATOs have to be manually reset.
