42" of the ground. Hrmm....
I was planning on doing 36", since my two girls would be able to see it better. Btw, the tank that I'm planning on buying is 24" tall. (65 g breeder).
At my eye level, (I'm 5'7") I would see the top of the tank.
Now I'm thinking of moving it up a bit....perhaps build a bench for the girls to sit/stand on.
