IceCap Granular Activated Carbon (GAC) XLarge 15lb Box

IceCap Premium Granular Activated Carbon (GAC) — Bulk 15lb Box (IC-GAC-15BX)

The IceCap Bulk Granular Activated Carbon 15lb Box (SKU: IC-GAC-15BX) is an authentic, laboratory-grade chemical filtration media distributed by CoralVue to offer high-capacity, dependable water clarification across massive showcase displays, multi-tank fish rooms, coral propagation facilities, and professional service accounts. While mechanical filtration traps solid particles, microscopic dissolved organic waste naturally accumulates over time, turning your aquarium water an unsightly yellow tint and blocking vital light penetration from reaching demanding corals or plants. The IC-GAC-15BX serves as a highly efficient molecular filter, acting as a massive chemical sponge to lock away organic contaminants, foul biological odors, and dangerous chemical compounds before they can impair your ecosystem.

Unlike cheap aquarium carbons made from wood, lignite, or coconut shells—which either contain high ash levels that shift water chemistry or possess microscopic pores too small to trap complex aquarium proteins—IceCap utilizes premium bituminous coal. This material is high-temperature steam-activated to develop an extensive network of macro-pores optimized specifically for aquatic environments. Its high structural hardness ensures the granules resist crumbling under active flow conditions, making it perfect for passive placement in mesh filter bags or active fluidization inside media reactors like the IceCap INT or EXT series. Packed in a generous, commercial-scale 15-pound box, this bulk configuration delivers professional-grade clarity at an economical price point for heavy-use environments.

Key Features

• Maximizes Aquarium Light Penetration: Strips out yellowing organic humic acids that refract light, drastically boosting overall PAR delivery from your LED or T5 fixtures straight down to deep-water corals.

• Neutralizes Chemical Coral Warfare: Actively pulls out toxic terpenes and phenols released by aggressive soft corals (allelopathy) trying to stunt the growth of neighboring hard corals.

• Completely Safe for Reef Environments: Carefully factory processed to ensure it will not leach undesirable orthophosphates or heavy ash into high-salinity marine or delicate freshwater systems.

• (Note: This filtration package includes 15 pounds of loose premium granular activated carbon inside a bulk storage box. Fluidizing media reactors, mesh media bags, and water chemistry test kits are sold under separate product categories).
