Description
Achieve crystal-clear water and a healthier aquatic environment with ESV Granular Activated Carbon (GAC). Recognized by professional reef keepers as one of the highest-quality chemical filtration media available, ESV GAC is specifically engineered to remove dissolved organic compounds, toxins, and yellowing pigments from marine and freshwater aquaria without compromising water chemistry. The ESV Difference: Bituminous Coal Base Unlike cheaper, wood-based carbons that can be dusty or leach phosphates, ESV uses a premium bituminous coal base. This material provides the ideal balance of: Optimal Pore Size: Specifically sized to trap the organic molecules most commonly found in reef tanks. High Surface Area: Maximizes the “adsorption” of pollutants, ensuring long-lasting filtration. Low Ash Content: Minimizes the impact on alkalinity and prevents unwanted pH spikes during initial use. Key Features & Benefits Phosphate-Free: Rigorously tested to ensure zero leaching of phosphates, preventing the fuel source for nuisance algae growth. Superior Hardness: The high hardness level of these granules prevents them from crumbling into fine dust. This eliminates the risk of “carbon dust” circulating through your system, which has been linked to Lateral Line Erosion (HLLE) in sensitive fish. High Flow Efficiency: The large, uniform particle size facilitates excellent water movement through media bags or reactors, preventing clogging and ensuring maximum contact time. Plankton Friendly: The specific grain size is designed to help prevent the mechanical removal of beneficial planktonic food organisms, making it ideal for high-end reef systems. Certified Quality: Meets the stringent requirements of the American Water Works Association and Food Chemical Codex. Usage Instructions Preparation: Briefly rinse with RO/DI water to remove any minor surface dust generated during shipping. Application: Place in a fine-mesh media bag in a high-flow area of the sump, or for maximum efficiency, use in a dedicated fluidized media reactor. Replacement: For optimal performance, replace every 2–4 weeks, or when a “yellowish” tint begins to return to the water (visible by looking through the length of the tank). Specifications Size: 15 oz. (Approx. 425g) Material: Bituminous Coal-based Granular Activated Carbon Application: Marine, Reef, and Freshwater Aquariums
