Doug,
I got excited on the first page and had to message after seeing the tank picture; not realizing I am few years to late. I love the DD tanks but would never buy them with the 2 cornerflo... I enjoy looking at my tank from the sides and seeing hugh overflow boxes is something I am learning to hate on my current tank (they take up way to much square footage for a simple 1.5'' drain. I think it's great how you got your tank custom made. I wish larger companies like aqueon and perfecto would start producing starphire aquariums like marineland in standard sizes.
Did you have your LFS order the tank for you or did you deal with marineland directly? How much would you say a custom tank of your size/design would cost going with another company vs marinland?
