So I found Post of facebook market of someone in my area that's building fish tanks on the side... I asked for 2 estimates a 6x2x2H and a 6x30"x18"H she said for both tanks it would only be 300 so about 150 each and she would use 3/8 glass... I then asked her if she would brace it and she said she would have to order it but she could which to me means that she was gonna build those tanks with 3/8 glass and no bracing... To me this didn't sound safe? But on the other hand what if I could get her to use 1/2 and brace it would the risk be worth it? The risk being how well can she build it.
