Tunze Osmolator nano ATO noise and quality question

[coloradoreefer94]

For my ATO, I am between the Tunze Osmolator Nano and the nano 3. Is there a big different in noise generated and the overall quality? Theres about a 30$ difference and I am assuming the "v3" has upadated features?

Older version has a noisy pump and new one does still have a hum to it.

Get the new one if noise is a concern.

Agree with the poster above, if noise is a concern get the Nano3.

Also spare parts may not be available for the older model in few years, so the new one may be better option going forward.

As for features both models work the same, older model use float switch the new model uses optic sensor. From my experience functionality is the same, the nano3 feels like a refined design.

Good luck,
