And I thought it wasn't going to be this complicated... Well, I do want a glass show tank as opposed to a tub. I live in an air conditioned house in Kentucky, USA. I will keep doing research and post my proposed system and see what everyone thinks, see if it will actually work. In the mean time, I need to keep learning.

So, in this setting, what is the best course of action for heating? You mention in the post above that I may need UTH on both ends. If this is the case, how does one keep 1/3 hot (90 degrees), and the rest cooler (80's)? Sorry if I seem totally lost but this is turning out to be a little more complicated than I thought.
