I don't know if you're wrong or right
But will say, Elos tanks have 2 sheets of glass
For their bottoms
Their newest stands, made of aluminum only touch the edges of the tank
There is nothing under the glass otherwise
I don't think there are enough of them, say relative to Red Sea tanks, where I think I have ever heard of a problem with them(but they did redesign their stands)
They are shorter than Red Sea tanks as well, 20 inches or so
As to a bottom that overhang the stand, like I said, I am putting a 3/4" HDPE sheet between the stand and the neoprene underlayment, which will lip over as you suggest
If I had the CurrentUSA the OP has, I would do the exact same thing. It is a good price for a tank that size
SCA and Glass Cages used to be the down and dirty tank makers. But Class Cages has gone premium
CurrentUSA tanks used to be premium, now down and dirty
