I have a 40 gallon tank I am trying to cycle. It has no live rock atm because I didn't wanna pay 12 a lb for it. My last tank I cycled with live rock. My issue is that I am reading 0 ammonia but my nitrates are consistently reading 250 and nitrites at about 40. I have done 2 50% water changes in the last week and no change on my readings. It's been about 2 months now. I tested my water with 0 across the board. I tested my mix with a reading of 10 nitrate and zero nitrite. I am using reef crystals BTW.... Any ideas?
