Osmolator 3155 vs 3155 nano

[BristleWormHater]

Can't find to much info on the nano version. Does anyone have experience with it? Does it have the same safety features and alarms?

If by nano you mean the 3152, have used these for years even on larger tanks.
No controller box or alarms, a single float switch that triggers the pump when water falls below a certain level, automatic shut off after either 2 minutes or 5 minutes (you can choose the setting).
I prefer the 3152 over the 3155 due to less points of failure... and the fact that a used one came with my first tank (90g) 10 years ago and still works flawlessly (Other than replacing the pump, but it's the same pump the 3155 uses).

Not sure if this helps, but there are other threads in the Tunze forum that might be of interest
