hey iv been fishless cycleing my tank for a month and half now. my tank will now process 3 ppm of ammonia in a 12 hour period. Im only adding ammonia every 24 hrs. every night my ammonia and nitrites will both be at zero so i will add 3 ppm ammonia. 12 hrs later in the morning my ammonia will read zero but my nitrites show about 5 ppm. i will test again 12 hrs later that night and both ammonia and nitrite will read 0ppm. Its been doing this for about a week now. Is my cycle done? or do i need to wait untill my nitrites are zero 12 hours after I dose with ammonia. let me know your thoughts. my PH is 8.2 and i just dropped my water temp down to 76 degrees. Thanks
