I am currently on day 12 of cycling a new 10 gallon tank. Most of what I went through with my goldfish is here:

Well on Sunday morning I noticed Elmo had died having gotten stuck to the filter intake. He was looking lethargic the day before, probably from too many nitrites, and I think that was what made it possible for him to get stuck. I had found an article on the web that talked about doing fishless cycling using fish food instead of ammonia:

Today I finally received my testing kit and when I tested both ammonia and nitrites it said they are at 0! I didn't expect that. I can't yet test for nitrates, but this must mean that my bio filter is working to some degree, as it has cleaned up after Elmo, right?
So, do I need to get another fish or do I continue to feed the tank for another week or two? I don't have access to the ammonia needed for chemical cycling...
I just didn't expect to see NO ammonia or nitrites, so I'm kind of confused.
