It's getting sooo frustrating and i've been so paitent this entire time. On Sunday my tank will turn 7 weeks old, and the cycling still isint over. I'm going through a nitrate spike right now, i just tested it a few minutes ago, and it was still high, but has gone down some. How long does it take for this spike to go back down. I'm really wanting my readings to show 0 but it feels like i'm never going to get there. It's just really agravating.
