I'm glad you got him a 10 gallon though :D
If it's cycling, you'll need to do more than 10% water changes every so often - that wouldn't be enough on most cycled tanks!
A cycling tank usually needs at least two 50% changes per week, but it is best to invest in your own liquid test kit so that you can measure ammonia, nitrite and nitrate yourself, and see when levels are getting dangerous.
