Saw this holding tank video and....

This topic may have been touched on before but I haven't found much so I'm looking for a little advice. Namely whats the largest sheet I can install and at what thickness. If I remember correctly I read somewhere that the panel will bend fine as long as the radius is 200x the thickness.

If I go by the 200x assumption then 1/4"-3/8" should work fine, but of course the major concern will be the hydro pressure on a panel that is too big. Any ideas? With acrylic sheet around $125-$200(depending on size) and the tank at $600 (cheaper if you can find one on craigslist) it seems like a easily build huge tank, all that's really needed is a jigsaw and a dream.

1/4" might bend enough, i don't think 3/8" would flex enough

If you notice in the video he used polycarbonate which is more flexable and stronger then acrylic. Depending on the radius 1/4" would probably bend enough, hard to say on the 3/8" it depends on the sheet size. By the way 1/2" polycarbonate is bullet resistant.

The pressure depends on what level you place the window. If you place it near the bottom the pressure would be greater. If you place it higher up the pressure would be less.
