Do I need to adjust my Specific Gravity?

Yes, but not by very much...although I'm having difficulties wrapping my brain around that right now.

Ah, that's why it took so much salt. That's a lot of water volume. After the initial cycle, your tank should never have ammonia or nitrite. The presence of either is called a mini cycle, and means that you have done something to either damage the biofilter or you have added new critters which are demanding a bigger biofilter and it will take a bit of time for the biofilter to catch up.

I have to disagree with this, as it is one of my pet peeves. Ammonia and nitrite are always present. It is undetectable test readings which are desired, indicating extremely low levels of both.
