I was well on my way with cycling 29 gallon tank nitrites finally dropped from its spike ammonia was processing down nitrites were 80ppm then ammonia stopped processing all together I was advised to do a 50% water change I did that added prime with water I put back in. now nitrites have not come back at all ammonia is stuck and nitrates are about 40 nothings happening anymore I’m at a loss should I just start over? another water change? no clue at this point i’m so far in the cycle and I think it’s completely crashed going on 7 weeks. oh and ph has never moved always stays 7.2 give it more time to process ammonia? did I kill all the BB?
