Should be plenty thick, even with the 5' length of glass you have very little water depth, so little internal pressure on the glass.Rimless, I think you can get away with 8mm.
I think 8 mm glass is a good idea, and even then I would have a central brace on a really long tank.Yep, thickness of 8mm is for my preferred safety rating and as little deformation over length as possible.
Hi all,
