Do you mean nitrItes or nitrAtes? Most likely, your tank is undergoing a cycle since the addition of your LR. This is completely normal. Just let the cycle finish, do a water change, and you'll be all set.

Unless you're already aware of the steps of the cycle and how it works, I recommend you use the search function at this site and perhaps gather a bit more information about it. :happyfish
