I started cycling a 50 gallon tank on May 1st. On May 18th, I started getting nitrites, with it showing off the charts from May 24 thru June 1st. Ammonia started going down so I was adding 1 tsp each night to bring it back to 4, then it would go down to 1 by the next night. The nitrites started dropping and were at 1.0 from June 4-9, then from the 10th-13th they were .5. Now I tested today, and they were back to 1.0 and the Ammonia has not dropped since I added the usual amount on June 11th. The only thing different I did was I added the ammonia at midnight on the 11th where I have been typically adding it at 7:00 pm. That shouldn't make any difference should it? Other than that, I did nothing different. Why did the ammonia not go down this time and the nitrite went up a little?
Cycle stalled?

Have you been feeding the ammonia daily since May 1?
Have you done a water change? (I assume not but ask just to be sure)
The fact that your nitrite went up could be good, although it is strange that your ammonia didn't reduce as per normal.
Have you started to see nitrates yet?
