Okay so I have finished cycling. My ammonia is at 0, nitrites at 0, and nitrates 0. I’ve been cycling for about two weeks using bio spira and dr Tim’s ammonium chloride . I dosed at recommended 2ppm and was reading about every 2 days. The first week my ammonia’s began to go down and nitrites began to rise. After my nitrites began to lower my nitrates began to rise. Eventually I noticed my nitrates began to disappear these 2 days and now today I am read 0 nitrites and 0 nitrates. I’m confused as to what happened. I have been keeping my lights off for the most part (except maybe 20 minutes a day mfor the view). What could it be ?
