bro when i did mine the filter broke with the last 6cc's and i got some residue in it. at first it was cloudy but when you let it sit for a few days the residue deposits at the bottom and the liquid is crystal clear. i baked mine at 200 for 20 minutes, then let it rest for 15 minutes and repeated for 10 minutes. i have been using this fina for 3 weeks and everything is perfect. just let the residue sit at the bottom and don't shake the bottle before drawing.
