Nano Heater Recommendations

[Autumnsky]

A while back I read some recommendations for an adjustable nano heater for a 6.6G or 5G tank. Can't remember which brand, it seemed one not commonly found in the big box stores.

Any how, what brand do you prefer?

Would like to get an adjustable, submersible one.

I have a 6g pillar tank with a Cobalt digital heater. I love it!

Saw that for sale, probably ordering tomorrow, I will eventually need two, so I will pick up one tomorrow, and see what everyone says before I get the other one.
