I'm diving into my first serious woodworking project: constructing a stand for my 50-gallon aquarium. The stand dimensions are 36x36x20, and I've got a guide to follow, but I'm a little unsure about using 2x4s. I want to ensure the wood is sturdy enough to support over 500 pounds without warping. I've got a 10" miter saw and a sander but no fancy tools to straighten the lumber. Can I use HD 2x4s, and how long should I let them dry before assembly?

Definitely go for kiln-dried lumber; look for ones labeled KD. When you stack them, make sure to place 1/2" slats in between each layer to allow airflow for acclimation. A moisture reader can help too—aim for 6-8% moisture content for furniture lumber. Use your 2x4s for the framework, and consider adding side panels for a polished look, even if they might increase the cost and weight a bit. Grab a drill and some 2.5" deck screws, and you'll be set!
2x4s are pretty standard, so you'll likely be fine with the HD ones, but it’s best to choose higher-grade lumber like #1 or select if you can find it. Take your time at the store to pick out the straightest pieces without knots. You don’t need to wait forever to let them dry; a few days should do, but just make sure to watch for warping once they're assembled. Adding a piece of plywood on top can really help distribute the weight and level things out, and definitely stick with screws and glue for added stability. Good luck with the project!

Thanks for the drying tips! I’ll definitely look into a moisture meter. I’ve got a drill, so I’ll grab those deck screws. I was on the fence about side panels since I’m unsure if the extra cost is worth it. Maybe I’ll build the frame first and see how it looks!
