The AquaFX Granulated Carbon GAC Filter 10 x 2 is a crucial second-stage filter media designed for reverse osmosis (RO) and reverse osmosis/deionization (RO/DI) systems in saltwater aquarium setups. This hand-packed granulated activated carbon filter effectively removes 99% of chlorine, bad tastes, odors, fluoride, pesticides, herbicides, and other volatile organic compounds (VOCs) from your source water, providing a clean foundation for your reef tank. It is engineered to process a substantial volume of water, ensuring high-quality input for sensitive marine environments.

Crafted from sustainable coconut shell carbon, this filter boasts a 30% longer lifespan compared to standard carbon blocks, capable of processing up to 5,000 gallons of water at 2ppm chlorine. Its unique hand-packed, loose media design prevents channeling, ensuring maximum contact time and filtration efficiency. The refillable shell adds to its sustainability, while robust specifications include a maximum water temperature of 140F (60C) and a maximum pressure of 120PSI, ensuring durability and consistent performance.

This 10 x 2 inch GAC filter is an ideal choice for reef aquarists utilizing AquaFX RO/DI systems such as the Barracuda, Dolphin, Moray, Mako, Octopus, Hammerhead, Great White, and Whale Shark, as well as most other residential RO systems with standard 10-inch canisters. By effectively pre-treating your source water, it protects subsequent RO membranes and DI resin stages, extending their life and ensuring the purest water for your aquarium. For optimal water quality and system efficiency, it is recommended to replace this filter every 4-6 months.
