What brand of biopellets are you using? You may want to remove some of the pellets and do a decent water change to help dilute the food source. I would also add some fresh activated charcoal. The cloudiness should be gone in a day or two. You want to have the pellets sizzling no dancing like a lot of the videos on the web. When you look at the pellets you should insure that visually you see water moving around the pellets.
