Hey guys... Quick background... I'm cycling a 10 gallon tank for the last month or so. I used some filter media from my larger tank, and ammonia (same ammonia that cycled my other two tanks). As of last Friday, my nitrites disappeared along with ammonia, I was cycled. Since i wasnt ready for fish yet, I kept the cycle going during the last week by dropping in ammonia every day, but missed the last two days. I tested the tank last night and all of a sudden, the nitrites are off the chart! Ammonia is still disappearing, i dosed last night and it was gone tonight, yet still high nitrites. Only thing I did with the tank between last Friday and today was add a sponge over the filter intake and a large stone. Any reason why my cycle would suddenly revert back to not being cycled? It's such a pain because I was planning on getting my fish tonight
