In the planning stage yet have a mountain of 2x4 and 2x6s haven't decided which I will use. Tank dimensions will be 84"l x48"w x 24"h. The piece of glass I plan to use is out of a 125 gallon it's tempered and 72"x23"x3/8 thick. Will this hold? Also I was looking at a pond liner from amazon a total pond epdm 40 mil for $115. Any recommendations regarding the liner? I will post pics of the plans once I have them finalized. It's gonna be a slow build.
