I had placed a small piece of shrimp in the tank the other day, and yesterday I had an ammonia spike. According to the test kit, it hit somewhere between 0.25ppm and 0.50ppm. This morning's tests showed no ammonia and no nitrites, but nitrates are now up to about 10ppm. Having never cycled with 100% live rock before, this seems too fast and I'm hesitant about considering the tank cycled (For comparison, my last tank was cycled with all dry rock and a couple pieces of live rubble. The tank sat for somewhere between 8 and 10 weeks before I added a clean up crew, then sat for another 6 weeks before I added my first fish).

The tank will likely not see a clean up crew until mid April anyways (hopefully the algae doesn't get too insane before then). I have to wait for classes and exams to be over and I've found a job for the summer.
