Thinking of building a new stand for a 6' long, 125 gallon reef tank full of rock w/ about 3-4" of sand. The reason for the new stand is I would like for it to be higher then the average stand and no middle braces. Thinking of useing 4"x4"x48" corner posts with 2"x8"x72" for the top and 2"x4"x72" along the bottom. Thoughts? Is 2x8 good? Should i use a 2x10?
