Hey guys! So I’ve had my 20 gal long tank since Feb. 7 of this year and everything was cycling well with some semi-established media. Then on March 1 I found a decaying cockroach in one of my tank decorations.
Since removing the roach and decoration I have done two massive water changes and subsequent ones as needed to lower the off the charts ammonia. However, even when I get it down to 0 ppm it climbs back up on its own.
Before all of this I already had some Nitrites and Nitrates and then the cycle stalled. Two days ago my Nitrites finally converted into Nitrates but the ammonia is not budging. Thank you for any help. If you need more info from me let me know.
