ok this might seem like a dumb question, but is it normal for nitrates to fall when you are cycling a new tank? i thought that only happens when you do a water change. ammonia is 0 and nitrites is about 2 and nitrates just went from between 60-50 to about 20. is this normal?

I dont know about SW, but for freshwater it is...I hope someone comes along with sw experience to help....I cant imagine that as far as a cycleing of a tank its much different but I could be wrong

THis is normal. It means your tank is converting the nitrate into nitrogen.

is that good or something to worry about?

That is what it is supposed to do.
