Thats great, They feel better because there was ammonia in the other tank and they have more room now.
Just keep checking your water daily, as soon as you see ammonia start with the daily water changes.
Edit: I re-read, I see you do have ammonia readings, so daily changes are in order.
Test your water right before a water change, keep a log, this will help determine where in the cycle you are.
Here's a basic explanation of the nitrogen cycle:
First your ammonia will rise, in a few weeks you'll see the nitrite levels rise and the ammonia levels start to drop. After a few more weeks you'll see the nitrate levels rise and the nitrite levels drop.
Ammonia and nitrites are toxic to your fish. So until your cycle is complete, you need to keep the levels down with daily water changes
When you having readings of 0 on both ammonia and nitrites with some nitrates showing, your cycle is done.
Then you can go to a normal weekly maintainance schedule.
