Your tank won't continue cycling if there is nothing in there to produce
waste. You could possibly continue cycling the tank without fish using a
procedure known as "fishless cycling" - this is where you add small
amounts of ammonia to the tank and continue testing as if there are fish
in there - once you reach zero nitrites and ammonia your tank will be
cycled - never tried it myself but there are a lot of people who swear by
this technique as it doesn't involve any stress to fish.

A good place to ask any of your questions is:-

Thanks much. Don't want to add more chemicals if I don't have to. The only
ammonia I have is 10% ammonium hydroxide "janitorial strength" that I use to
clean out plugged ink-jet printer heads.

I'll follow up on your link, but have never used Google groups.
