hey folks - I am a newbie. I've been cycling my tank for three months now. My ammonia is under control but my nitrite spike never dropped. It's a 66 gal tank with large sump. I am using dry rock and sand. My ammonia drops to zero but nitrites have been 5+ for a month, and my nitrates are around 20 ppm. How come the nitrite level never dropped and how do I get it to do so? There is no live stock in the tank. Help is appreciated.
