Last time I added ammonia was about 4-days ago. Not sure if that is the right thing to do or not? I did it to "test the system" so-to-speak. I added enough to take ammonia to right at 2ppm and it was gone in about 12hrs.

In my first saltwater tank (10g) I added a single small fish. Nitrites pegged the test kit for like many many weeks. When I stopped adding food it took about 4-5 days before nitrItes dropped down. They dropped down to 0 in 2-3 days. And remained at 0 when I resumed adding food.

Hopefully your nitrItes will drop down soon.

Finally...today the tank finished cycling. I added a little amonia to check and see if it is good. Hope to add fish this weekend.

Not sure if it helped, but I added Dr Tim's nitrifying bacteria Friday.
