This is the first time I've ever leveled it a tank. It wasn't hard to get it to where it is now, but I would have needed hubby to produce different shims for me to get it more level. I don't know what kind of aggravation that would have involved.
I just used a Stanley Fat Max level.
As an aside . . . What is a "shell" as it relates to glass? That is a totally new term to me.
