Hello, so I really want to build a shallow reef tank. My main goal with this tank is to house tang(s) and some other slightly larger fish. I want the tank to be roughly 5-6 feet in length and about 12-18 inches in length with about 12-18 inches in height (note: for the height and the width if one of them is 16 then the other will be 12, etc. I don’t really want them both being 16. Right now I am leaning towards the height being either 12 or 14 and width maybe being 16). Another alternative to the tank dimensions is a tank that is about 4 feet by 4 feet by about 12 inches to 18 inches (with 16 being more common). I plan on building this tank using glass sheets from Home Depot and Lowes. However, their glass sheets are not past .125 inches in thickness. I am worried because I obviously don’t want the tank to burst. I am also unsure if the glass is tempered or not. Will this matter too much (the glass being tempered or not)? If the glass is too thin, I am OK with the tank being only 12 inches tall because I saw on a few forums that if the glass in thin, then the tank needs to be shallow. If the glass is .125 in thickness, could I accomplish something like a 72 inch length by 16 inch width by a 12 inch height? I really want to build a nice shallow saltwater tank, this is also going to be my first saltwater tank as well. Also, the glass sheets are going to have to be connected together. As in, if two sheets are 36 inches long, then I will silicone them together for both the front and back panel. And the bottom panel will also be a combination of 3-5 separate sheets all siliconed together. Will this be an issue if the individual panels are made up of separate sheets? To increase the glass thickness, is there anyway I can layer two sheets on top of each other to increase the individual panel thickness or will this not work? I do not plan on going smaller than .125 or 1/8 inch thickness glass and if need be, I am fine with the tank only being a foot tall. Thank you in advance!
