i really don't understand what happened with yours, especially since nitrites were processing post-water change, yet now they're really high. and you would've thought the A-bacs would by now be able to process all the ammonia.
at +17 hours nitrite is now 1ppm.
I wonder if I dose as soon as nitrite reaches 0ppm, whether it will encourage the N-bacs to grow faster. But then its not possible on weekdays as I'll be at work hmmn
