ATO choice

[HM3105]

Trying to decide which ATO for my nano, approximately 40 gallons AIO.

Tunze is the gold standard. I have one and no complaints.

I use a Kamoer on my nano and it’s performed equally as well.

I used the tunze 3152 for many years, but recently switched to the AutoAqua Nano for my new build. I must say, aesthetically it is more pleasing but both do the job just as well.
