I vote option 2 as well! Very cool dimensions. How big is that room? I think it looks really small and to make it smaller with the tank IN the room would be a shame. You need room with a big tank to look at it from a good distance and take it all in.
I usually feel jealous of the big tanks (around 300G) but not this one

I just cringe at the cost of lighting and maintaining it! Actually even more when I think of the time it will take to maintain it...Your brave
Going to be amazing though to watch someone else take this on. I would never want a tank this big but I love seeing them
So your not building this one yourself though right?
