I'm so excited, I checked my water this morning and my nitrites are finally to zero. My nitrates are 100+. My question is what do I do next? I'm thinking I'm ready for a major water change. Please let me know what you think.

Now that you have no nitrites and high nitrates do as big of a water change as possible to bring the nitrates down then retest and see where your at.

yup! 75+% water change is what i would do too!
Course I always continue to feed ammonia for an extra 3 days and check in 24 hour increments to make sure that ammonia & nitrites ARE in fact 0 within 24 hours each time BEFORE doing the big water change. Better safe than sorry as my mom used to say

I've been dosing ammonia to 4 ppm everyday and for over a week it's at zero in less than 24hrs. Today is the first time the nitrites were zero. So you think I should keep dosing to 4 ppm for a few more days (and checking) before the large water change?

I dont think you need to dose anymore ammonia. Seems like youve had a pretty strong cycle judging by your nitrate readings. Just do multiple water changes (40%-50%) each til you get it down to a non toxic amount.
