I have been trying to recycle my new tank, yesterday was the 9th day. However , the ammonia is still 4-5.Why hasn't it started to drop yet? However, nitrite has already gone to 50. I don't have any nitrate yet. Could it be because my filter is second hand? How do I know if the filter is working well, or should buy a new one??
