Building a 75 gallon tank stand is easy. I made one last summer. What i did it used four 4/4's in each corner and then made two 2/4 frames and drilled them in to the 4/4 pretty simple design but over built. But thats a good thing. The i wrapped the stand with 1/4 inch plywood and put molding on top and bottom and then i put a 1/4 inch top on it. It looks great and is functional and accommodates a 35 gallon sump underneath. Hope that helps. Good luck!
