Go ahead and turn it off.  Your greatest liklihood of problem is if you
have accumulations of unmetabolized detrius or food in your substrate that
could evolve accumulations of H2S when they go anaerobic.  If you've
recently vacuumed your substrate (before turning off the UGF), you have
less of a chance of this situation.  Of course, if the tank is heavily
planted, vacuuming the substrate can be difficult, and may not be
advisable.  If the tank IS heavily planted, you probably don't need to
worry too much about accumulations of anaerobic decay because of the
plants' root systems.

I nixed the UGF in my 55g about 2 years before I re-did the tank and yanked
the plates.  I had no problem with the results, although I had a bad algae
problem, probably due to the beef-heart food I was feeding my angels and
