Large Tanks (101gal+)

This ones taken some thought and heres what iv got in mind:

Layout

Im consolidating systems and have closed my previous 5' reef system. I now have a clear vision of a well developed coral display tank and this is how i want to go about it.
Im restricted to a 5'x2' floor print even though i desperatly wanted to take out a section of living/dining room wall and go for a 5'x4'. My wife agreed i could have a nicer finish and exactly what i want if i stick to the 5'x2' so i choose this...
