No - stop adding ammoniaSo now that the Ammonia is finally coming down I am trying to decide if I should follow @GARRIGA comment and add more NH4Cl back to 2 ppm and continue waiting for it to be able to drop that in 24 hours.
You don't need to process 2ppm of ammonia in 24 hours unless you plan on adding a lot of fish at once - like over a dozen. A single fish, or a couple of fish doesn't make that much ammonia.
Let your ammonia clear, maybe do a water change to reduce nitrate if you need to and add a fish or two.
For context, I once pre-cycled a tank until it was processing 2ppm in 24 hours. That tank I stocked with 17 fish (2 to 3 inch size) all at once and never saw a rise in ammonia (to me that means all those fish produce less than 2ppm ammonia)
