IceCap ROX 0.8 Premium Activated Carbon, XLarge, 15lbs
SKU: IC-ROX-XL
Pharmaceutical-Grade Adsorption: Highly porous extruded micro-pellets pull dissolved organic compounds, odors, and toxins out of the water column with unmatched speed.
Low-Dust Extruded Pellets: Remarkably hard pellet structure resists tumbling degradation, drastically reducing fine particles linked to HLLE in fish.
100% Phosphate-Free & Acid-Washed: Processed with high-grade hydrochloric acid to eliminate ash content, preventing unwanted algae blooms and pH spikes.
Maximizes Aquarium Light PAR: By chemically removing yellowing tint layers from the water, it restores crystal-clear transparency to maximize lighting penetration to deep corals.
Concentrated Visual Efficiencies: Ultra-dense internal surface area requires roughly half the standard dosage volume of low-tier granular activated carbons.
Freshwater and Saltwater Optimized: Safe and highly recommended for sensitive marine reef environments, freshwater planted aquascapes, and multi-tank filtration systems.

IceCap ROX 0.8 Premium Activated Carbon — Bulk XL 15lbs
IceCap ROX 0.8 Premium Activated Carbon (SKU: IC-ROX-XL) is an authentic, pharmaceutical-grade chemical filtration media distributed by CoralVue to deliver crystalline water clarity and elite chemical safety to massive multi-tank configurations, large public-scale aquariums, maintenance service routes, and high-volume marine installations. In any closed aquarium system, water naturally develops a distinct yellow or green hue over time caused by decaying organic particulates, fish wastes, metabolic phenols, and defensive chemical compounds (allelopathy) released by competing corals. Standard granular activated carbons (GAC) are frequently fragile, irregular, and loaded with fine ash dust that clogs filters and causes health issues. IceCap ROX 0.8 completely eliminates these limitations through an advanced extruded engineering profile.
The defining characteristic of the 15-pound "X-Large" bulk product box configuration is its professional-scale utility and exceptional economy. The "0.8" designation denotes the exact micro-millimeter diameter of the extruded carbon cylinders, a specification optimized to maximize accessible exterior surface area while preventing water tracking or bypass channels within large media chambers or commercial sump grids. Because it undergoes a comprehensive hydrochloric acid wash during treatment, it carries an ultra-low ash index and guarantees zero phosphate leaching. This prevents the nuisance hair algae spikes common with lower-tier carbons. By scrubbing the water grid of complex yellowing agents, it optimizes photosynthetically active radiation (PAR) levels, allowing your primary lighting systems to penetrate straight to low-tier corals for optimal tissue growth.
Key Features:
Bypasses Traditional Carbon Dust Rinsing: Superior structural hardness prevents the micro-pellets from grinding against one another, ensuring minimal fines during transit and storage.
Counteracts Defensive Coral Toxins: Actively captures volatile compounds released by aggressive soft corals and anemones before they can stress delicate SPS corals.
Elite Multi-System Wholesale Value: Heavy 15-pound bulk packaging yields massive long-term operating cost savings for aquarium service professionals and shop systems.
Note: Because this carbon is incredibly potent, it requires roughly half the physical media dosage by volume compared to standard bituminous or lignite carbons.

Instructions:
- Open your 15lb bulk box of IceCap ROX 0.8 carbon. Prepare your chosen large-scale media vessel, industrial filter sock, canister partition, or commercial fluidizing reactor.
- The Quick Rinse Phase: Although ROX 0.8 is one of the cleanest carbons available, always place your required dose into a fine-mesh bag and perform a brief, gentle rinse with fresh RO/DI water to clear out microscopic shipping fines. Warning: Never aggressively rub or crush the media pellets during rinsing.
- Calculate Your Dosage: Use a precise dosage baseline of 1 tablespoon per 10 gallons of total aquarium water volume (approx. 1/2 cup per 100 gallons). Note: If a large display has never run high-grade carbon or has highly visible yellow water, start with a 50% half-dose to prevent sudden lighting transparency shocks to your corals.
- Media Reactor Placement: Place the rinsed carbon inside your media reactor column firmly sandwiched between two dense foam padding layers. Adjust your internal water flow so the media is packed down tightly and does not fluidize or tumble. Constant tumbling will grind the hard pellets and create unwanted fines.
- Passive Sump Bag Placement: If running passively in large commercial sump baffles, place the carbon into a high-grade mesh bag rated below 500 microns. Position the bag directly into a high-velocity flow section to force maximum water turn-through.
- Replace the media entirely every 2 to 4 weeks depending on your unique biological load, fish populations, and coloring indicators. Keep the bulk box liner tightly sealed between uses to prevent atmospheric moisture and scent loading.
Pro Tips:
- Utilize the "White Paper" Test to Accurately Track Carbon Exhaustion. It can be hard to judge water clarity just by looking through the front glass panel of a massive aquarium. To test your carbon's effectiveness, hold a crisp piece of bright white printer paper against the side glass panel of your tank and look horizontally through the opposite side. If the paper appears yellow or green, your ROX 0.8 carbon has reached its absorption limit and needs to be replaced. If it looks perfectly crisp and white, your media is still actively filtering.
- Pack Your Media Reactor Tightly to Prevent Long-Term Grinding Fines. While traditional carbon types are sometimes allowed to gently boil or tumble inside a fluidizing reactor, you should always pack IceCap ROX 0.8 tightly. Because these pellets are exceptionally dense and hard, allowing them to constantly rattle and tumble against one another will slowly shear off their outer edges, creating ultra-fine black dust that can escape into your display tank. Keep your reactor sponges snug and lock the media down.
- Store the Bulk Box in a Cool, Dry, Chemical-Free Environment. Activated carbon is an incredibly effective gas-phase adsorbent. Because this 15lb bulk case will likely last several months or years on single systems, keep the inner heavy plastic liner sealed airtight with a heavy zip-tie between refills. Do not store this box in a garage or cabinet alongside paint thinners, fuel cans, open laundry detergents, or harsh chemical cleaning fluids. The premium carbon will gradually absorb these airborne volatile organic compounds right through unsealed packaging, exhausting its adsorption capacity before it ever hits your water.
