Hi all, first post here. I'm a returning hobbyist after being away for 10 years and I've run into a problem with my cycle. I have a Waterbox 20 AIO that was started at the end of March 2021. Approximately 15 lbs of CaribSea Life Rock, 15 lbs of Caribsea Arag Alive Special Grade sand, and a dozen or so ceramic bio balls in the center chamber. Fishless cycle; seeded day 1 with 4oz Dr Tim's one and only and I've spiked with Dr Tim's ammonia chloride per the Dr Tim's schedule. I'm at about 50 days into the cycle give or take and the cycle still has not fully completed. I have high nitrites that will not drop, like max on my API test kit (5.0 ppm+). I've also had my lfs test the sample with similar results. Late April 2021I reseeded 4oz of Dr Tims. I also respiked with ammonia chloride (to 2 ppm) to test if 2 ppm ammonia would be converted within 24 hours, it was not, more like 1 ppm was converted. I do have nitrates, around 60 ppm. So the tank has technically cycled but the conversion of ammonia is extremely slow and high nitrites are present. Not sure how to proceed here or what to do. I'm old school and would like to see my ammonia and nitrite at zero and able to convert quickly before adding any livestock. Thanks!
