Froggy was right on the money. Wait until your ammonia reaches zero before adding any more ammonia. And when you add ammonia just do a capful. A tablespoon may be a bit overkill, but will still work.
Personally, I think the only time you should continually add ammonia is during the nitrite cycle...after ammonia levels have dropped to zero. I think you add way too much ammonia by continually adding ammonia during the ammonia cycle.
For example, on day 1, you add a capful of ammonia to bring your levels to 5 ppm. On day 2, you have 4 ppm, so you add another capful. How much ammonia do you have on day two (after adding more ammonia)? 9 ppm!!! On day 3, enough bacteria has established to consume 3 ppm, so you add another capful? How much ammonia do you have after the capful? 11 ppm!!!!!
(9-3+5) So you see where this is going....The bacteria isn't keeping up with the ammonia being added. Eventually it will, but I don't think a week is sufficient time for the bacteria to colonize. Of course, if you seeded your tank, you could possibly get enough bacteria in a weeks time. My example is for illustrative purposes. I do not know the reproductive rate of bacteria. I can only assume that bacteria reproduce at some exponential rate. And since ammonia is not increasing, the bacteria will eventually colonize enough to consume all ammonia added. I just don't think bacteria would be able to consume all bacteria within a weeks time without seeding.
IMO and IME, it's much more logical to bring your levels to 4-5 and let things ride until ammonia drops to zero. Then, during the nitrite spike, you shoud add ammonia to keep the bacteria happy.
