Laguna Filter Media Bags (2) are perfectly sized to fit most pond filters. Placing the filter media in the bag provides an easy and convenient way of installing media inside the filter chamber.
When the media is completely exhausted, you can easily remove and replace it with a new bag. The mesh material can hold most loose filter media, such as Laguna Pond Peat and Barley Straw, and allows water to pass through it thoroughly. It comes complete with a fastening seal.
Designed to hold loose filtration media of nearly any type, such as Biospheres (bio balls), or Biomax Media.
Includes (2) 8-1/2" x 14" black mesh bags with (2) plastic closure fasteners.
