I transferred all my live rock and filter media with a cup of my old sand into my new tank from my old tank. 29 to 29 gallon. The rocks were out of water for probably maybe a minute. The tank has been running with everything for about 2 days. I thought I would have had an instant cycle but my API test kit shows .25 maybe .50 ammonia with 0 nitrites and 5-10 nitrates. Why is there ammonia in the tank without nitrites? I'm thinking the ammonia present is from the die off of the live rock. My old tank had been up for over a year+. Not sure what to do.
