Which ATO

[Brad Shook]

I am adding an ATO to my 20g tank. There are too many options to pick from. I am considering Ice Cap ATO or
TUNZE
OSMOLATOR NANO 3152 AUTO TOP OFF.

I would appreciate some feed back on real world use and recommendations.

I use the 3155 osmolator and love it. It has a
Float switch and optical sensor for added security. It can be dialed down for nano tanks also.

Smart micro is a solid choice. I run two on two different tanks and they’re awesome.
