large tank and euro bracing

[Bryan]

Honestly, I don't know. InterAmerican tends to overbuild their aquariums for strength so I guess it's for extra protection. I think he mentioned that they brace width if the tank is over 18" wide.

I think you would be fine at 1/2". I think the majority of the bracing is just the leftover from the tank construction. they will brace whatever they use to make the tank.
