My tank finished cycling about two weeks ago and I added a Bristlenose Pleco about three days ago and the water has been cloudy for the past two days. I have no nitrites and no ammonia in the tank, and I haven't checked my nitrate levels yet. I did a 5 gallon water change yesterday, I think helped a little but I am not sure. I really don't want to use chemical clarifers or anything like that, except maybe using biological clarifers.

Any thoughts? Could my tank be going through a mini-cycle?
