Thanks guys, helpful info.
Pacu Mom, thanks for the kind compliment and yes I've seen this tank and enjoyed reviewing these threads again. It looks like we don't know the manufacturer or I've missed it. Anyone knows???
The 3" acrylic viewing window is excellent but $50,000 for a 14'x7'x6' would be too much for me. As stated I got two 4500 gal Dolphin FG 13'x13'x4.5' with 8'x4'x2.5" window for $32,000 for both with better physical footprint and adequate viewing for my purposes.
