Its your bacteria working to break down the depris. its the end product. What it will do is sep out and float to the top. Or when you put your sand in air bubbles got trapped under the sand bed.

I would say so, mine didnt take that long. I say it took about 2 months then I noticed air bubbles coming from the sand bed.
