Question for anyone..I am cycling a 25 gal FW tank. My nitrites are at 0, nitrates are between 100 and 130, my ammonia drops from 4-5ppms to 0 48 hrs after I add ammonia. Is the tank cycled or do I need the ammonia to drop to 0 in 12 hrs???
 
Ya thought that was the case just thought it would take less time for the ammonia to 0 out, but I have added ammonia about 8 times since the initial ammonia nitrites 0'd out and it always takes 24 to 48 hours for the ammonia to return to 0???
