nice, i got a 70" x 18" piece of 12mm plate glass for 150$ from st. catherine's. figured between 10mm and 12mm, i'd rather go for the slightly stronger one as i won't have any bracers separating it into 2 windows, just single long one.[/QUOT
For my 300 ply tank, I got my 93"Lx30"H piece of 12mm (1/2") glass for $240 from a place in Dundas, Ontario.
