Pictures taken.
The tank measures 18 feet long and holds 1350gallons (not including the 250g sumps/refugium)!!!!
Below is an example on how thick the glass is of this monster tank. Below is a 2"x4" next to the tank (compare thickness of 2x4 to thickness of glass) holding up two 125g tanks, one will be used as a sump and the other as a refugium.
So the total water volume of this reef setup is 1600 gallons!

So how thick is this glass (that's my pointer finger)?

More pictures tonight 
135g Main Tank/ 125g Frag tank with 55g sump.
