Red Sea REEF-SPEC™ Carbon is one of the most respected reef-specific carbons in the saltwater aquarium hobby and a staple at The Coral Boutique. Engineered specifically for marine and reef aquariums — not generic freshwater — it strips the organics that even the best skimmer and mechanical filtration leave behind, so your water stays crystal clear and your light reaches your corals at full intensity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMost carbon on the market is built for general-purpose use, but reef tanks have unique demands: ultra-low phosphate leaching, ultra-low ash content, neutral pH impact, and the right granule size and pore structure to target reef-specific organic pollutants. REEF-SPEC™ delivers on every metric. Its unique micro\/macro porous structure rapidly adsorbs proteins, fats, carbohydrates, organic acids, and phenols — the same compounds that fuel nuisance microorganisms, drop your Redox potential, raise CO₂, lower pH, and yellow your water (cutting the blue and near-UV light your corals depend on for growth). The optimized 0.6–2.3 mm granule size with 1000 m²\/g of total surface area provides a high adsorption capacity for both small and large organic molecules, and because it leaches virtually no phosphate, it won't fuel nuisance algae the way lower-grade carbons can. The result: cleaner, more transparent water, brighter coloration, better light penetration, and longer replacement intervals than non-reef-specific carbons.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRapid removal of organic pollutants and yellow tint from reef water\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eHigh total adsorption capacity for both small and large organic molecules\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eUltra-low phosphate output (0.000001 g\/ml) — won't fuel nuisance algae\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eUltra-low ash content for minimal dust release\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eNeutral pH impact — won't shift water chemistry\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eImproves light penetration in the blue and UV spectrum that drives coral growth\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAdsorbs medication residuals after treatment\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRemoves residual ozone when used post-ozone reactor\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLasts longer than generic activated carbons — more cost-efficient over time\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSuitable for marine, reef, and freshwater aquariums\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFilter bag included (250g and 1000g sizes)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQuick Stats \u0026amp; Specs\u003c\/strong\u003e Product Name: Red Sea REEF-SPEC™ Carbon Manufacturer: Red Sea Available Sizes: 100g, 250g (9 oz), 1000g (35 oz) Granule Shape: 0.6–2.3 mm flakes Density: 0.48 g\/ml Total Surface Area (TSA): 1000 m²\/g Pore Volume: 1.04 ml\/g Small Organic Adsorption: 1000 mg\/g Large Organic Adsorption: 280 mg\/g pH (in distilled water): 8 (neutral \/ reef-safe) Phosphate Output: 0.000001 g\/ml Compatibility: Marine, reef, and freshwater aquariums\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDosing \u0026amp; Replacement:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRoutine maintenance (organics \u0026amp; yellow tint):\u003c\/strong\u003e 50 g (100 ml) per 200 L \/ 50 gallons for 1–2 months in a moderately stocked reef\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePost-medication treatment:\u003c\/strong\u003e 100 g (200 ml) per 200 L \/ 50 gallons for 1 week to adsorb medication residues\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOzone post-treatment:\u003c\/strong\u003e 50 g per 50 mg\/hr of ozone injection at the ozone reactor \/ skimmer outlet\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eReplacement schedule:\u003c\/strong\u003e Every 1.5–2 months, or when carbon volume reduces by ~50%\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSize Coverage Guide:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e100g:\u003c\/strong\u003e Ideal for nano reefs, AIO tanks, and small marine aquariums up to ~100 L \/ 25 gallons\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e250g:\u003c\/strong\u003e Sized for mid-range reef systems up to ~1000 L \/ 250 gallons (or shorter intervals on smaller tanks).

Place in a media reactor (best results) or filter bag in a moderate-flow area — recommended flow is 1000–1500 LPH (250–400 GPH) per 50 g of carbon.
