REEF-SPEC Carbon’s granule size and its structure, ensures a very high total adsorption capacity and rapid extraction of the specific pollutants that are found in Reef aquariums. Red Sea Reef Spec Carbon is Available in 4 Different Sizes Reef Spec 2000 ML Reef Spec 1000 ML Reef Spec 500 ML How does activated Carbon filter water? Carbon removes the organics from water by a physical process called adsorption. Within an aquarium, the submicroscopic pores of activated Carbon is the final stage of the filtration process, adsorbing the organic molecules that are too small to be removed by by protein skimming. Red Sea's Carbon is Clean/Clear Competitor's Carbon Organic Load & Yellow Tint Removal The recommended dosage of Red Sea’s REEF-SPEC Carbon is approximately 50 gr (100 ml) per 200 L (50 gallons) for a period of 1-2 months for a moderately stocked reef aquarium. Organic Load & Yellow Tint Removal The recommended dosage of Red Sea’s REEF-SPEC Carbon is approximately 50 gr (100 ml) per 200 L (50 gallons) for a period of 1-2 months for a moderately stocked reef aquarium. Post-Medication Treatment The recommended dosage of Red Sea’s REEF-SPEC Carbon to adsorb medication residuals is approximately 100 gr (200 ml) per 200 L (50 gallons) for a period of a week. Post-Medication Treatment The recommended dosage of Red Sea’s REEF-SPEC Carbon to adsorb medication residuals is approximately 100 gr (200 ml) per 200 L (50 gallons) for a period of a week. Ozone Post-Treatment The dosage of Red Sea’s REEF-SPEC Carbon to remove residual ozone is 50 gr per 50mg/hr of ozone injection. The carbon should be placed at the ozone reactor/ protein skimmer. Carbon should be replaced once it has reached 50% of its original volume. Ozone Post-Treatment The dosage of Red Sea’s REEF-SPEC Carbon to remove residual ozone is 50 gr per 50mg/hr of ozone injection. The carbon should be placed at the ozone reactor/ protein skimmer. Carbon should be replaced once it has reached 50% of its original volume. Usage tips The adsorption activity of the Carbon media relies on a good Carbon/water contact, and therefore moderately active water flow will increase the efficiency. Strong water flow will reduce the contact time and interfere with the adhesion process of the organic molecules to the Carbon. Strong water flow may also cause the granules to grind against each other, releasing Carbon material to water. Remove any fines, by rinsing Carbon under tap water. Due to air trapped in the pores Carbon will float, and therefore it is recommended to soak the Carbon in RO water until all of the air has been released. Place the Carbon in a location with an active flow of 1000-1500 lph (250-400 gph) per 50 gr carbon. Replace Carbon every 1.5 – 2 months. Note: When Carbon becomes saturated with organics, it may start adsorbing some of the trace elements from the seawater. ## Features - Rapid removal of organic pollutants - High total adsorption capacity - Ultra-low phosphate output, ultra-low ash content - Suitable for marine & freshwater - Filter bag included. - Age range description: All Stages ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ETGMW7Y | | Allergen Information | Nut Free | | Best Sellers Rank | #83,876 in Pet Supplies ( See Top 100 in Pet Supplies ) #419 in Aquarium Filters #1,324 in Aquarium Filter Accessories | | Brand | Red Sea | | Brand Name | Red Sea | | Customer Reviews | 4.7 out of 5 stars 218 Reviews | | Global Trade Identification Number | 00730773374205 | | Included Components | all | | Item Form | Flakes | | Item Type Name | Filter Carbon | | Item Weight | 1.5 Pounds | | Liquid Volume | 2000 Milliliters | | Manufacturer | Red Sea | | Manufacturer Part Number | 37420 | | Model Number | 37420 | | Target Species | Ornamental Fish | | UPC | 730773374205 | | Unit Count | 1 Count | ## Product Details - **Brand:** Red Sea - **Item Form:** Flakes - **Item Weight:** 1.5 Pounds - **Liquid Volume:** 2000 Milliliters - **Manufacturer:** Red Sea ## Images ![Reef Spec Aquarium Carbon 2000 ml – Superior Activated Carbon for Marine or Freshwater, Eliminates Toxins & Odors, Crystal Clear Water - Image 1](https://m.media-amazon.com/images/I/61usux3gafL.jpg) ![Reef Spec Aquarium Carbon 2000 ml – Superior Activated Carbon for Marine or Freshwater, Eliminates Toxins & Odors, Crystal Clear Water - Image 2](https://m.media-amazon.com/images/I/81qjlu+z+dL.jpg) ![Reef Spec Aquarium Carbon 2000 ml – Superior Activated Carbon for Marine or Freshwater, Eliminates Toxins & Odors, Crystal Clear Water - Image 3](https://m.media-amazon.com/images/I/51CFCDEAwaL.jpg) ![Reef Spec Aquarium Carbon 2000 ml – Superior Activated Carbon for Marine or Freshwater, Eliminates Toxins & Odors, Crystal Clear Water - Image 4](https://m.media-amazon.com/images/I/41AtWyXTKuL.jpg) ![Reef Spec Aquarium Carbon 2000 ml – Superior Activated Carbon for Marine or Freshwater, Eliminates Toxins & Odors, Crystal Clear Water - Image 5](https://m.media-amazon.com/images/I/71ZNMxT+pdL.jpg) ## Questions & Answers **Q: Organic Load & Yellow Tint Removal** A: The recommended dosage of Red Sea’s REEF-SPEC Carbon is approximately 50 gr (100 ml) per 200 L (50 gallons) for a period of 1-2 months for a moderately stocked reef aquarium. **Q: Post-Medication Treatment** A: The recommended dosage of Red Sea’s REEF-SPEC Carbon to adsorb medication residuals is approximately 100 gr (200 ml) per 200 L (50 gallons) for a period of a week. **Q: Ozone Post-Treatment** A: The dosage of Red Sea’s REEF-SPEC Carbon to remove residual ozone is 50 gr per 50mg/hr of ozone injection.
