Well Im getting alittle antsy to get a bigger tank again. I have a few questions for some of the DIY guys/gals. Im planning on building my next tank. I have narrowed it down to 2 sizes, 48'' x 30'' x 20'' or 36'' x 30'' x 18''. Either way this tank will be RIMLESS GLASS. My question is what thickness should the glass be? Could I use 3/8'' on a rimless? or is this pushing my luck? My guess is atleast 1/2'' on the 48'' long tank. What do you think?

Thanks
Dustin
