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

Key features

• 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.
