Instead of the shrimp, just add enough ammonia to get a positive test
result. If it drops to zero within a day, you are cycled. During the time
the ammonia is dropping, you may see a nitrite positive, too. They should
both drop to zero within a day.

It's been 2 weeks. I'm thinking about getting a cocktail shrimp to see
if the ammonia spike happens.
