So my 14 gal Bio Cube has been up and running for 10 months. I have been having trouble keeping my Nitrates down, I normally do a 2 gallon water change per week, but I decided to do a 3 gallon last week. The next day all my corals looked terrible, and like they were dying. I checked my parameters and besides my ph being around 7.4 and my nitrates between 10 and 15 ppm everything else was 0. I added some ph buffer and brought my ph up, the next day most of my corals looked a little better, I did lose some zoa's though. So I decided to check my parameters again and all of a sudden I have .05 ammonia, 0 nitrites and 10 to 15 nitrates. I do another 2 gallon water change the next day then check my parameters, I was shocked to see my ammonia up to 1.0, 0 nitrites and again 10 to 15 nitrates. Any idea what could be causing this? I have a goby and green emerald crab, both accounted for, and various hermit crabs and snails, so I don't think it is from something dying. Could it just be my test kit? Shouldn't I be seeing some nitrites? Any help would be appreciated.
