I've used the Neptune ATK, Red Sea ATO, and this Tunze Nano Osmolator. The Tunze was much less reliable and would often have the float stick and not properly maintain water level. This happened from the moment it was installed and was not due to lack of maintenance or buildup on the float sensor.

After a couple of weeks it failed to trigger. After a quick unplug/plug it recognized it was low and filled up. Make sure to keep an eye on it! Otherwise a must have for a nano

This is my first ATO, and I can't saying anything bad about this product. I no longer worry (overly) about my salinity changing due to evaporation. if this product goes defunct, I probably will upgrade to the non-nano version, but Tunze has a quality ATO product for those with nano systems.

Love this little ATO, been using mine for 2 1/2 years with no issues.
