Starting to turn my attention towards the stand for this beast. I plan on doing it out of 2x6s with a solid plywood deck on top for the tank to rest on. With that said, should I put some sort of thin padding such as felt maybe between the plywood and the bottom of the tank? I will undoubtedly have to physically get inside the tank at some point and don't want any risk of busting something. Although 3 sides will be fully visible, I will only have full access to both short sides. The back will be up against a wall and the front will be built into a different wall so I won't be able to reach the center of the tank.
Ive always been an advocate for acrylic directly on plywood. No foam, no rubber mat, just straight on the wood. If ur stand or tank is unlevel u can use an additional sheet of ply on top but not screwed down then shim inbetween that sheet of free floating ply and the sheet thats screwed down to level the tank as needed. Shims are ur friend lol… theres no such thing as too many IMO if there needed. Rule of thumb for bracing a stand for acrylic is no larger than 24” apart to support the bottom.
