Do a 20% water change to lower your nitrate.

And your good to go. Add some fish
although he has nitrates it is over a unit of time greater than 24 hours more than likely. in order to ensure the cycle is complete you must re-test to make sure that ammonia turns into nitrate in 24 hours. That is when you know the cycle i complete.
Do not add fish until your sure that your cycle is complete by performing the secondary test we have described.
