Good morning Lori my fish friend :)
Nitrates should be less than 20ppm's (you are in a safe area right now) in your tank and the only way to fix them is by doing the water changes. I would test your tap water as well...see what it reads straight from the tap.
Your ammonia should be at zero and it will get there...also through water changes.
Your getting there...sometimes it can take up to 8 weeks to cycle...patience and consistency are always key :)
