IceCap Black Drawstring Media Bag, Large

IceCap Large Black Drawstring Media Bag

The IceCap Large Black Drawstring Media Bag (SKU: IC-DMB-3443) is an authentic, high-utility filtration containment pouch distributed by CoralVue to provide a flexible solution for handling bulk loose media. Many chemical resins—like granular activated carbon (GAC), granular ferric oxide (GFO), or specialized nitrate removers—are sold in bulk jars without individual application bags. Tossing loose chemical granules directly into an open under-cabinet sump or filter tray will lead to media washing straight into return pump impellers, which scores ceramic shafts, breaks delicate needles, and clouds your display tank with black dust. The IC-DMB-3443 solves this by providing a reliable, heavy-duty containment boundary that locks down your chemical or biological media while keeping your water path fully open.

Measuring an expansive 13 by 17 inches, this large-format bag offers the extensive structural volume required to hold large portions of biological media, bulk carbon charges, or large-capacity ion exchange resins. While traditional media pouches rely on white fabrics that quickly stain a muddy yellow-brown or utilize metal zipper tabs that rapidly corrode and seize when exposed to high-salinity reef systems, IceCap utilizes a stealth-black premium nylon weave. Sealed tightly by pulling a heavy-duty cord drawstring closed, the bag completely removes any metallic dependency from your water loop. Pliable and tough, it can be tucked flat inside heavy external canister filter trays, laid down beneath filter sock discharges, or placed across high-flow overflow channels for optimal contact time.

Key Features

• Prevents Channeled Water Bypass: The generous 13x17-inch surface area allows media to be spread thin and flat across your filtration tray, forcing water to flow uniformly through the bed rather than cutting around a dense clump.

• Resists Organic Staining: Deep black fiber construction hides unsightly organic brown mold and yellowing compounds, keeping your filtration room looking clean.

• Easy Media Replacement: When chemical media becomes exhausted, simply slide the tension lock open, shake the spent granules into the trash, rinse the bag under a tap, and refill it.

Note: This item covers one standalone large black nylon drawstring bag. Loose chemical media, biological ceramic spheres, and filtration cups are sold under separate product lines.
