So after some serious re-consideration, I am scrapping the
Peninsula part of this tank. The room just doesn't work well enough to incorporate the tank properly, and I think in the end it would look very out of place where I was originally planning to have it.
This means the tank design has been edited. It will be 2 sides viewable (1 long (60") side, and the short (36"

) end). This change in design
might allow me to run Starfire on both viewing panels, I'll have to get an update on the cost. The 2nd long side will now become the back of the tank where I will run 2 of the 4 return lines from my closed loop, the other 2 will still come up through the floor and be hidden underneath the rock work. Overflow will stay at the end of the tank, no real changes there, other than adding my sump return line up through the overflow box. So I will have water returning through 3/5 panels of the tank.
I will also be incorporating a 20-25G viewable refuge at the end of the stand (down where the mitre saw is sitting in the pics).
Couple pics to give you an idea of where the tank will be sitting now. My 75G is directly behind me from where I took the pics.
That's all I can think of for now for an update.
