Placement Of Tank?

[Reef Pilot]

I like the 1st diagram for placement. You want it accessible and viewable as much as possible, for maximum enjoyment. It won't get the same attention downstairs.

I have 2 tanks, one upstairs in the kitchen right in front of the island counter, and one downstairs. The upstairs one always becomes the main gathering place whenever we have friends over, and I can look at it often, too.
