Mike,
It is a good article however I do not agree 100% with the second last paragraph simply because when fishless cycling, the major advantage is to add all your fish at once. By adding ammonia, you will build a very large bio and if you only add a few fish in at a time, the bio will die off because there is not enough 'food' for all the bacteria.
Of course, when I fishless cycle, I add quite a bit of ammonia and after 3 weeks I do a water change. By that time, the ammonia would of completed its cycle and the nitrites would be maxed.
