£35.99
Red Sea REEF-SPEC Carbon (2000ml/1000g) is specially formulated to meet the exacting needs of marine and reef aquariums. With its ideal granule size and unique micro/macro porous structure, this high-quality carbon offers exceptional absorption capacity, quickly removing organic pollutants, toxins, discoloration, and odours from aquarium water. The result is outstanding clarity and a healthier environment where fish, corals, and invertebrates can thrive.
Unlike many standard carbons, REEF-SPEC Carbon is designed with extremely low phosphate leaching and minimal ash content, ensuring that it does not affect the delicate pH balance of your aquarium. Its longer-lasting performance also means fewer replacements are needed, making it a cost-effective solution for maintaining pristine water quality.
For best results, rinse the carbon thoroughly before use and soak in RO water to release any trapped air. Red Sea recommends a moderate water flow of around 1000–1500 LPH per 50g of carbon to achieve maximum efficiency without material breakdown.
The 2000ml/1000g pack provides great value for larger systems, making Red Sea REEF-SPEC Carbon the ideal choice for serious reef keepers seeking unmatched water quality and stability.
