IceCap String Net Media Bag — 8" x 13" (SKU: IC-SNMB-813)
The IceCap String Net Media Bag (SKU: IC-SNMB-813) is an authentic, durable chemical filtration housing accessory distributed by CoralVue to streamline media management inside heavy-volume marine reef sumps, multi-tank central systems, freshwater pond configurations, and commercial holding facilities. Running bulk chemical and biological media is one of the most effective ways to polish water and maintain a pristine ecosystem, but finding a large enough containment vessel can be a challenge. Standard small fine-mesh fabrics often trap heavy detritus, clog rapidly, and choke out vital water flow, creating stagnant water pathways. The IceCap 8in x 13in Net Bag features an open, structural grid weave that maximizes water turnover while ensuring your loose media stays securely contained exactly where you put it.
The primary structural benefit of the IC-SNMB-813 rests on its Reef-Safe Drawstring Closure Framework. Built completely without toxic metal zippers or metal eyelets that oxidize and leach heavy copper or rust into closed systems, this non-corrosive bag utilizes a durable pull-string lock. This allows you to load loose bulk carbon or biological media quickly, tie it down, and drop it straight into high-velocity flow lanes. Measuring an expanded 8 inches by 13 inches, this high-capacity media pouch can be washed out and reused through dozens of fresh filtration cycles, making it a reliable, cost-effective staple for large-scale aquarium maintenance.
Key Features
Prevents Sudden Water Channeling: The open string net pattern forces water to sweep through the entire media core rather than just pushing around the outside.
Protects Expensive Pump Impellers: Keeps granular fragments tightly locked away, preventing loose rocks or carbon chunks from lodging in active pump motors.
Streamlines Media Rinsing: The open netting allows you to flush away production fines and shipping dust under your RO/DI line quickly before placing the bag in your tank.
(Note: This retail package includes (1) empty 8" x 13" String Net Media Bag with an integrated drawstring closure. Bulk activated carbon, GFO, and bio-ceramics are sold under separate product categories).
