I have keep checking with my NO2, NH3 and PH but it always the same. From the other topic I know the N-cycle should be N02 up then down. then No3 up then the N-cycle should be finished but I don't know how come all the reading always the same in last 2 weeks. I haven't check the NO3. I know I should check that as well. but the NH3 in my tank is high. I guess the N-cycle has not finish yet. Am I right?
