Now im almost done building my stand, its 7 feet long and 33 inches wide. As you read this keep in mind im no carpenter and this is my first time building one. It looks sharp and will deffinetly support the tank, i used 6X6 PT posts and 2X4's for the structure following UrauJoeys youtube video instructions. Although, i dont know if the wood was warped or if my cuts were off, long story short its bowing about an 1/8th of on inch in the middle. My dad, a carpenter, was telling me to put down foam (used under floors when building a house) and then put some 3/4 inch oak ply wood on top to create an even surface when the tanks on it. Does anyone have any suggestions on what i can do to make sure the glass doesnt warp and crack. Also, i dont have the tank yet, im either building it out of glass or plywood. if i used plywood for the tank, would it be less likly to crack if the stand isnt perfectly level? Any suggestions or ideas would be helpful. Thanks for your time reading my post
