1 ppm ammonia is too much. That will start killing off all the microfauna that is on the rocks and add to the cycle. Do waterchanges or you can add an Ammonia detoxifier which changes NH3 to NH4 which is much less toxic. The nitrifying bacteria don't care. Keep in mind that many ammonia test kits read Nh3 and NH4 as total ammonia and will give you a "false positive". Seachem ammonia Alerts are compatible with detoxifiers.
Here's a great read that's pretty accurate (first page anyway):
