Im going to buy materials this weekend and still unsure about the bracing. Tank is about 600 gallons, its 8' long 4' wide and 30" tall. I am using 3/4" birch and pond shield. Ive seen several threads and videos but not exactly how to brace it with 2X4s. Im good with the bottom and top, worried about the sides, front and back. What distance should a place every 2X4? Should I assemble the plywood together then build the wall supports or vice versa? What about the front with the glass panel, any bracing needed. If someone can help me understand exactly what to do I can get the lumber and start going to work, thanks
