Unlike standard granular activated carbon (GAC), which is often irregular and dusty, ROX 0.8 is a highly refined, extruded pelletized carbon. This specialized manufacturing process creates a remarkably hard, dust-free media with an internal pore structure that is significantly more accessible to water-borne pollutants. ROX 0.8 doesn't just clear the water; it chemically \"scrubs\" it, removing dissolved organics, coral toxins, and medications with unmatched speed and efficiency.\u003c\/p\u003e\n\u003cp\u003eThe \"0.8\" refers to the precise size of the pellets, which are optimized to provide the maximum possible surface area while still allowing for excellent water flow-through. Because it is acid-washed and features an ultra-low ash content, IceCap ROX 0.8 will not cause the pH spikes or phosphate leaching common with lower-quality carbons. It is the ideal choice for \"mixed reef\" systems where corals are in constant chemical competition (allelopathy), and for any aquarist who demands the highest level of water clarity and safety for their inhabitants.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtruded Pellet Design:\u003c\/strong\u003e Uniform sizing ensures even water flow and prevents the \"channeling\" common in irregular granular media.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Adsorption:\u003c\/strong\u003e Higher iodine and methylene blue numbers mean it pulls pollutants out of the water faster than standard carbon.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Dust Formulation:\u003c\/strong\u003e Requires minimal rinsing and won't release fine particles that have been linked to HLLE in fish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhosphate Free:\u003c\/strong\u003e Extensively processed to ensure it doesn't fuel algae growth in low-nutrient reef systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight Penetration:\u003c\/strong\u003e By stripping yellowing compounds, it increases the PAR levels reaching your corals at the bottom of the tank.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhen To Change:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Maintenance:\u003c\/strong\u003e Due to its high efficiency, ROX 0.8 should typically be changed every 2–4 weeks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe \"White Paper\" Test:\u003c\/strong\u003e If you look through the length of your tank at a white piece of paper and see a yellow\/green tint, your carbon is exhausted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eROX 0.8 Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWashed with Hydrochloric Acid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIodine number:\u003c\/strong\u003e 1000 min.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall-pan hardness:\u003c\/strong\u003e 97 min.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface area (BET):\u003c\/strong\u003e 1300m2\/g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle size:\u003c\/strong\u003e \u0026lt;0.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAsh content:\u003c\/strong\u003e 1%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMethylene blue absorption g\/100g:\u003c\/strong\u003e 24\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSmall 1\/4 Gal Container: 0.75 Lbs of media\u003c\/li\u003e\n\u003cli\u003eMedium 1\/2 Gal Container: 1.5 Lbs of media\u003c\/li\u003e\n\u003cli\u003eLarge 1 Gal Container: 3 Lbs of media\u003c\/li\u003e\n\u003cli\u003eXL Bulk Box: 15 Lbs of media\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eInstructions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick Rinse:\u003c\/strong\u003e While ROX 0.8 is very clean, a brief rinse with RO\/DI water is recommended to remove any shipping-related fines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e Use 1 tablespoon per 10 gallons of total water volume.
