Glass thickness i need for diy sump?

[Duzzy]

Hi there,

was wondering what thickness glass I need for a sump 600mm x 300mm x 400mm high also here is the overflow I am building thanks to the net :-) http://www.reefs.org/library/diy/diy_winner1.html

Building a new cabinet (larger) to house sump, co2, and bits and pieces is bottled co2 and equipment expensive to set up?

That's about a 20g tank ... well just look at the thickness of the 20g tanks you see around.

I'd probably go for something around 3/16" (5mm) thickness of tempered glass.
