I used to almost never level my tanks and I've been pretty lucky. I notice the bowfront tanks MUST be level or else they WILL leak. But on a regular rectangular tank, if it's slightly unlevel, it should be ok... no?
if by slight we are talking very very very slight, then yes its fine. anything more then 3 degrees will probably cause some kind of break, crack, small leak, etc
