Euro bracing

[425nm]

I want to build two 24" by 24" by 16" tall aquariums that I will plumb to the same sump. I also wish to euro brace both of these (I know tanks of this size don't have to be braced but I would like to do so anyway), what thickness, type (tempered? regular glass?) and length of glass should be used?

I haven't been able to find any calculators or really any explanations on how to determine this so more in depth answers are appreciate.
Thanks guys!
