I’ve reached zero ammonia three times but since nitrites have remained high I’ve continued to dose NITROCYCLE. I read somewhere that you should bring ammonia back up to one ppm until your biological filter can bring it back to zero in a 24 hour period. Kinda made sense to me and since I‘ve had nitrites anyway I decided to try it. Also, knowing that different bacteria convert ammonia to nitrite, than those which convert nitrite to nitrate, I figured the prior needed to be fed while waiting on the latter to do their job. Does this make any sense or am I WAY overthinking it
