IceCap Granular Activated Carbon (GAC) Large 2.5lbs

IceCap Premium Granular Activated Carbon (GAC) — Large 2.5lbs (IC-GAC-LG)

The IceCap Granular Activated Carbon 2.5lb Jug (SKU: IC-GAC-LG) is an authentic, laboratory-grade chemical filtration media distributed by CoralVue to offer highly efficient water clarification across large display tanks, multi-tank sump systems, and high-load marine reef setups. While mechanical filtration loops trap large solid debris 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-LG serves as an indispensable chemical sponge, locking 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 placement inside media reactors like the IceCap 120INT or 120EXT canister series. Packed in a rugged 2.5-pound storage jug with an integrated handle, this configuration delivers professional-grade clarity at a practical economy for owners of larger aquatic displays.

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 2.5 pounds of loose premium granular activated carbon inside a heavy-duty storage container. Fluidizing media reactors, mesh media bags, and water chemistry test kits are sold under separate product categories).
