I have had my tank for a month now and fish have been in the tank since the beginning. For the past couple of weeks my ammonia levels have been as zero, so I have been watching the nitrite levels closely. I do a little less than 30% water changes weekly which keeps the nitrites around .25 ppm. I haven't seen them much above that because of my water changes. The fish seem happy and have good color, so it seems like the tank is healthy, but I have been expecting to see the numbers dip towards zero and stay. This isn't the case. As of late my tank always seems to be a little cloudy which I thought was the nitrates starting to take over but when I test for nitrates its always at zero, which I thought would be the case because the nitrites never even got to zero. Anyhow, my question is am I being inpatient or am I doing something that could be preventing this cycle from taking place. I always treat the water for chlorine and Chloramine before I add the tap water, but now I am wondering if I'm not letting sit long enough and that is killing the bacteria....I don't know. Any input would be appreciated. Thanks
