Right now, if I stand flat on the floor I can put my arm over the top of the tank and down into it. Maintaining the 30" wouldn't be bad, I understand that the 40" would be quite a bit taller. Cleaning the bottom might not be a big deal. The tank would be recessed into the stand almost 3" with the sand bed below the top of the counter.. That gives me 37" above the counter top.
For those that haven't seen a picture, this is what I am replacing, I kind of agree with my wife, the tank does look a little squat in there.
