I'm a huge fan of Teflon tape. The white stuff is usually good enough. I use it everywhere. I've found that too much is worse than none at all. I work in an industry where pipe fittings and caps are used all the time. We rarely use sealants of any kind and simply tighten until it stops leaking. As I understand it the dope, tuff-gel, or Teflon tape is simply there to "lubricate" the threads. If tape is used then it should be applied in a clockwise direction such that as the fitting is tightened the tape tightens into the threads. If it is applied backwards it has a tendency to unwrap as the fitting is tightened.
I use as little as possible and usually find the 2 wraps is the minimum that I can get away with. Pull it tight. All water heaters have anodes, including the heaters in your home. I think it is a copper pipe/steel tank thing.
