I have a 58 gallon reef tank with 5 fish in it. Now I cycled the tank with bioballs in the sump and 100 lbs of Tatoka lr in it. I had perfect readings, and then I took some advice to get rid of the bioballs being that it would help me out in the long run. However that was 2 and a half weeks ago and my nitrites still read .25 ppm. Should this be a cause for concern?
