Ah, time to debate with mike. I agree it is to cycle the tank, but the spike depends on the rocks (surely you don't disagree) If the rocks have alot of life that is still alive then you don't want to allow the ammonia to spike past 1ppm because it will kill off the life. If the rocks have little life then you can let it spike then fall. Water changes are necessary to preserve the life if you have duters, crabs, "critters" still on there. If the rock is just algae, then you can let the Ammonia go. Wait for nitrite to drop to zero, then you are good to go.
