I think my tank finally cycled but now I have some odor. I added a piece of ceramic wood which I rinsed in old tank water and let it set for awhile before adding to tank. I noticed the smell the next morning. Been doing 50 % wc every 2 days. Filter was clogged but running when u came home from work it is back running again. I posted this in a different thread but was in a pre existing topic about decor so might get more help posting it separate. The smell is kind of earthy if I had to describe it.
