I am in the process of building a stand for my tank. I have started to question the materials that I have bought and need some reassurance that what I am about to do is ok. My plan is to build the heart of the stand out of 1x4 select pine using the rocket engineer model and wrapping the stand in 1/2” birch. Does anyone see a problem with the stand supporting the weight of the tank using the 1x4 instead of 2x4? I roughly figure the tank filled with water, sand, and rock to weigh somewhere in the ballpark of 300-350lbs but I could be wrong, please correct me if that is not inline. Any help would be appreciated.
