I've never heard of a 'stuck cycle' ... but then the last time I 'cycled' a tank was +20 years ago ... just let it all happen in its own time and pace ... never ever had 0 nitrate, always detect nitrite with my Hanna tester ... and ammonia is just a phase that curing water goes through.
I don't understand the rush to throw stock into the tank ;-)
