what thickness 6mm ok for a 53"x12"x12" tank
does it need to be toughened
does it need to be toughened
/saltaquarium.about.com/cs/aquariumd...lcustomtank.htm. There are a number of factors that go into the decision that are explained on page 2. (Obviously, I am thinking of building one myself.)
On a 5ft length though, without bracing, you are going to need something nearer 8-10mm...
