Glass thicknes for a 180g with 4x3 base?

[waynes world]

Hi all, i have asmall space in my kitchen which i want to make into a nice small fish community tank.

I am thinkig on a ply base and all glass sides, the glass i can get from two 4x2x2 tanks for the sides, cut down in length from one tank for the 3 foot ends. Now all the 2 foot high tanks over here are made from 10mm thick glass, rare to find 12mm glass tanks. This is to save on the budget from buying new glass.

So question is as the new 4x3 base tank is still going to be 2 foot high, is the glass still going to be safe enough as the height is th same so the water pressure isnt going to change all that much....or is it?

cheers

Glass thickness is based mainly on height and some on span. For the height of the tank you are fine. Aee you planning any support accross the top of the tank?

Definatley have brace supports, min 2, better getting on the look out for 2 donor tanks then. I need to finish the kitchen for xmas.

10mm will be fine for 2' high if braced well and evenly supported around the base. 12mm would certainly give you a better safety factor and margin for error though.
