My Nano

[AJ_77]

I have these "Thermal Compact" heaters, thin ones. A 75W in the 15 tall and a 50W in the 10g. No problems with these, and they are slightly less obvious in the tank due to their slim profile and lack of labelling - they have the faintest stamp on them, almost like a watermark.

I should mention that the small one is finicky, and lacks fine adjustment. The larger one is great, precise. I'm wondering if it's actually a 100W... I'll have to look more closely next time I need to go in there.
