30" tall is really the very upper limit for doing a tank in 1/2" glass if you brace the hell out of it. With my waterline 2" below I'm only supporting 28" of water pressure plus the bottom is euro-braced in 6" wide strips so there's 1" for the silicone to attach to the sides. With the bottom 1" and 2" waterline there's only 27" of unsupported glass.
Although I'm aware that I'm on the limit with 1/2" glass the cost would double for 3/4" glass and with a proper 2" steel frame I'm confident it'll work. I'm also basing my build off two other reefers with the same dimensions and glass thickness that have had long term (5yrs +) success with their tanks.

The quote is for 3/4" glass. 2 panels for 4x10 by 3/4" shapfire for viewing panels,as will be a room divider tank one panel of 4x10 for the bottom that is 2 3/4" panels laminated and 2 side pieces of 4x4 by 3/4"..and will be in the wall so does the have to be pretty so for that the tank will be framed with steel L profiles and lots of cross braces.its a bit scary so i think I will drop the hight to only 40"..another option was acrylic 1 1/2" for the same cost but I'm afraid of the acrylic bowing because of the 4 feet high and will be easier to scratch and in case that I want to change the house it will have to be cut in pieces and waisted so with the glass just cut the silicone and reassemble it..will research some more until then as this will happen next summer..
