Tunze

I use this one. A little pricey but works great.

I have been running a Smart ATO for a year now with no problems. Its super easy to set up and small. The alarm that can't be reset without powering off can be annoying but since its hooked up to my apex I just turn the outlet off and on no problem.

I run the tunze nano, very happy with it

I've got an Ultralife float switch that's about 15 years old now and it's still going strong. Just a set it and forget it type tool for me.. In the picture below you can see the switch attached to the back glass of my 10 gallon sump. The five gallon bucket on the right is the reservoir.

I run the Tunze Osmolator Nano $100 at Marine Depot. It is tated for tanks up to 55 gallons but I have run it on my RSM 250 (66gal) and now run it on my Reefer 450 (118 gal). It has run dry many times all I do is fill the jug with RODI water and reset by unplugging it then plug it back in and it works perfectly fine.

Tunze Nano. Been running mine for 14 months now. Also, they have a 2 year warranty and awesome customer service. My pump was being a little weird after a few months and they sent out a new one right away.

Tunze Nano. So far so good.
Ran the auto aqua smart ato for a year and it was nothing but problems, a lot of which was due to the glass between the eye and sensor getting salt and calcium deposits on it, preventing it from working.
The old mechanical float valve (like used in the tunze) is hard to beat. And the tunze has an anti-overfill safety shut off feature built in.

thanks for the input. i will definitely be getting the tunze nano.

How about Smart ATO micro? It is in pre-order in MarineDepot. The sensor is very small and seems a good choice for nano aquarium.
