Best nano ato

[Lps_lover12]

I have a 15g Fluval flex and I’m looking into getting an ato. Wondering what everyone recommends? I was looking at the tunze 3152 nano but lost interest since it doesn’t have a overflow sensor only the timer. I was also looking at the auto aqua smart ato but still not sure. Don’t wanna spend a ton and any help is appreciated!

I have the 3152, and the lack of overflow sensor hasn't been a problem for me. I've been using it for over 6 months now. :)

I use this on my setup and haven’t had any problems.
