Hi guys! I'm new to R2R and any advice will be appreciated. I am restarting my 90g after taking a break. I want to build a new stand and decided to make it out of wood. It will be 5 ft long and I dont want to have a center support and was wondering if anyone has a similar stand and if there was any sagging. I originally was gonna do 2x4 doubled up but now am thinking it needs to be 2x6. also I should note the top is 1.5" oak so 2x4 might work. let me know what you guys think.
