The 2 tanks are a 120g on bottom and 125g on top. The bottom tank is on casters to pull out for cleaning and other fun stuff. The top stand is 46" off the ground. I'm planning on using 4X6 on each front corner and no center support in the front. It will have a center and diag braces in the rear. Also the stand will get fully finished with a solid sheet for the back and sides. Im just not so sure about the front.
He really is fearless.
