I’m finishing fishless cycling Dr Tim for last 4 weeks. I had already ammonia down to 0.15 and nitrite down to 0. Based on the instructions I added ammonia 1.5 ppm, checked the next day (24 hours) if the levels are bellow 0.2 which would mean the cycling is done. Unfortunately after 24 hours my levels are still almost same as dosed, so I had to wait about a week for ammonia and nitrite to drop again. Than same scenario once again, added ammonia 1.5ppm, wait 24 hours, and it did not change to 0. Do I have to keep repeating this process (dosing ammonia 1.5ppm) til I’ll reach 0 in 24hr ? Not saying that I’m not patient, just want to make sure I’m doing it the right way. My nitrates are 40 ppm now, so I know it’s working. What’s your experience or suggestions please?
