I just went back and re-read your original post. DuH! Moving the tank is the source of your high nitrogens. Whenever a tank is moved it goes through a mini-cycle just like when its first set up. You lose a certain amount of the bacteria in the move as well as stirring up a lot of the nutrients that may have been trapped in the system. It looks like its starting to settle down now and the LR is probably helping.

Sorry about the confusion.
