I just started to cycle my 180 on Christmas Eve using dry rock, live sand, and dr tims one and only. I've been dosing ammonium chloride to manually spike ammonia for the cycle. Has anyone monitored thier ORP during cycle? I'm curious if there is supposed to be a drastic change once the Benificial bacteria populates completing the cycle. Any info is greatly appreciated!
