1 Gal Pico help with ideas.

[tranvictor]

So I have decided to jump back into the SW reef scene after 7 years away. To give myself a challenge I decided I want to do a 1 Gal pico, mushroom and zoo reef, in a glass mason jar.

My biggest challenges are maintaining proper heating, proper current, and evaporation, as you can guess there will be very little room within the jar for much of anything. Does anyone have any ideas on how externally heat, and circulate the water?

I am in my homework phase, so feel free to blast away with your ideas.

Thanks.
