How mcuh can I stock after cycle complete?

[kveeti]

If you are doing a fishless cycle using ammonia, and doing it properly, you can fully stock the tank when the cycle is done. If you do not fully stock at this time, then you are essentially reverting the tank to cycling with fish and will have to add slowly over time.

and doing it properly being the key words here.

Agree with TwoTankAmin – if you are doing fishless cycling correctly, you can fully stock your tank. The amount of ammonia you add in a fishless cycle is generally more than is produced in a fully stocked tank – within reason, of course, assuming somebody understands what it is to fully stock a tank vs. overstocking it.

Chris "Nomad" Cow refined and popularized the technique

and from Chris Cow himself:
The amount of ammonia added is far above that generated by a reasonable number of cycling fish, resulting in faster growth of the bacterial colonies, and larger colonies when you're finished. In practical terms, this means that your tank cycles faster (reports of anywhere from 10 days to 3 weeks, depending on the fish tank... compared to average of 4-6 weeks for traditionally cycled tanks), and that you can fully stock a tank when the cycle is complete.
