Aquatic Experts Mesh Media Bags – Large Hole 1/8" Mesh with Rustproof Plastic Zipper for Bio Balls & Large Filter Media (10" x 12", 2 Pack)

LARGE-HOLE 1/8-INCH MESH FOR LARGE MEDIA: These pond and aquarium media bags feature 1/8"" (5,000 micron) mesh designed specifically for bio balls, ceramic rings, lava rock, and other large filter media. Not recommended for fine media such as GFO, carbon dust, or resins.. DURABLE, REUSABLE CONSTRUCTION: Made from strong black mesh with reinforced stitching, these bags securely hold heavy biological media without tearing or stretching, even during repeated cleanings in ponds, sumps, or wet/dry filters.. RUSTPROOF PLASTIC ZIPPER: Each bag includes a corrosion resistant plastic zipper that keeps large media contained while allowing water to flow freely through the mesh in both freshwater and saltwater environments.. OPTIMAL WATER FLOW: The large hole mesh design ensures unrestricted flow, making these bags ideal for pond filters, sump chambers, wet/dry trickle filters, and other high flow applications where fine mesh would clog.. CHECK YOUR SIZE BEFORE ORDERING: To reduce returns, please measure your pond skimmer basket, sump chamber, or media compartment to ensure the selected bag size fits your system.
