WebLots of aeration will both speed up the cycling process and keep the smells down (cycling can be smelly!). The optimum level of nutrients for beneficial bacteria growth is 400 to 600 ppm of ammonia and 200 to 400 ppm of nitrite (per no less than 8 papers and two books). So high levels of either ammonia or nitrite do not stall the cycle. WebHi nitrites will absolutely slow and even kill your cycle, just like ammonia.
