Therefore, your biological colonies that have been building till the end will start to die off a bit. This usually shouldn't be a problem, and I'm sure there would be no ammonia or nitrite spike due to this. The thing I believe could happen is just a higher concentration of nitrates before your first couple of water changes, as the colonies adjust. No biggie, I'm sure, though! Just for the record, I'm doing my first fishless cycle, and I'm starting week 4, I add ammonia, and the next day at same time, there is still nitrite, and alot of nitrate. I just dose half original amount of ammonia again, which is at 0 again, daily. I hyppthesize this will keep the current colonies fed, but not over-do it. I'm only gonna have one 2" fish in a this ten gallon, anyway.
