Hello BunnyGirl.
Thank you for the compliment. The base you see is a custom built aquarium stand that I built for this cube tank 4 years ago. It measures 4 feet by 4 feet by 36" tall.
Since then I have built quite a few of them for other aquarium enthusiasts across the country and locally here in KC.
There's quite a bit involved in the process which would take far too long to explain here in print. It takes quite a bit of wood working experience and alot of power tools
Thanks again.
Sean
