Thanks! Yes, I used 1 inch pine. Although it dents and scratches easily, it's very affordable and I love the look of it. I think I may to a combination of what I did for my current stand and yours with the corners. I'll have to think a little on how I want to piece it together, but I will have a center support, that way I can also have a seam for cabinet doors. I'll have the 2x4s on their 'sides' for the tank and floor.
My 29 gallon tank stand is still bare-bone. Although it had some trim, but when I moved it after building the current 75 I never re-decorated it. But I can't do too much with it because I have a 10 gallon under it for QT.
Boy, am I excited to build another stand!
