My newly cycled 125 gallons tank is having a little nitrites problem.
After finding a female swordtail dead this morning I decided to check the water.
The ammonia was zero bur nitrites were 0.25. I did a 50% water change nwaited over an hour to check the parameters again n the ammonia was zero again but the nitrites was 0.25 again.
Even after the water change.
Any advice
