The Ammonia eating bacteria colony is growing and eating at a faster pace every day. Once they have turned enough ammonia to nitrites the second type of bacteria starts to colonize. The bad news is they take twice as long to get established. So your looking at 2 to 3 weeks more of close monitoring till things settle down. Hopefully the filter media and plant you got from another tank will cut that time in half.
