As far as bracing goes, Im not sure how to go about it. Ive seen other people run supports across the back on angles. Is this the best way to go about it? I dont know much about woodworking so Im sorry if these are stupid questions. lol I just want to get this right the first time!
if you dont have a compound miter saw, or at least some experience with a 45 and a circular saw, dont attemp it, you really dont need a triangulated and double braced frame using 4"x4" for a 75g but to me a 75g is my limit for basic frames, anything above would need a triangulated frame its absolutely a necessity in my honest opinion.
the best basic support is vertical, its very hard to split a board vertically versus horizontally or at the wrong angle, a perfect 45 with another perfect supporting 45 to creates a triangulated frame where the weight is distributed at multiple points, but a basically vertical braced frame is all you need.
i would do all 4 corners and both front and back center in 2x4 pine, also if you'd like just for good measure add screws into the stands old wood at the joints because these stands are air nailed together and over time and throughout a tank and stands lifetime have probably been moved and setup many times meaning those nails might have backed out a bit or lost their initial bite into the wood.
if you go to lowe's and buy the lumber there, the cuts on their huge saw table are only $0.25 so its very affordable to build or brace a stand, and they measure about 3-4x and also asking you about the length on the tape and also compensate for the blade thickness before cutting.
