theres a excellent chance, you will ruin your tank if you get to
aggresive, plus will the anode clear the cieling above the heater.

Yes, if you are going to do it, make sure you get the new anode first and
that it fits.. With a tall tank, you'll have to get a curved anode, or one
made up of short sections, which are connected. I've only replaced a
straight one, but have seen pictures of other shapes.

Once you have it open, may want to disinfect the tank as well. Search the
net for instructions. All it takes is a gal of bleach.
