1/4" acrylic for 8L' x 4W' x 1H'?

[DarkTang]

Hi all. I saw a used 1/4" acrylic for 8L' x 4W' x 1H' tank (240 gallons). Its euro braced. I was wondering if the thickness is good enough so it doesn't bow and god forbid water all over my floors. Here's a pic of it

Thoughts?

I built one way back when I was starting to learn about acrylic, not as long or wide, but I can give you fist hand experience... it did and will bow and IMO, that's a little to thin for the amount of water it will be holding back.
