Abstract
A flotation filter has an outer member that has a top section and bottom section that are hollow. The top section has an inner edge and an outer edge with the outer edge having a diameter that is adapted to slide up and down an inner diameter of a storage container. Connected to the inner edge of the outer member is an internal grid. The internal grid includes members that crisscross to provide spaced openings. Further, the internal grid dwells in a plane below a horizontal plane of a top surface of the top section.
