The AquaFX Carbon Block Filter 20 x 2.5 serves as the crucial second stage in your reverse osmosis (RO) or RO/DI water purification system. This high-performance filter is specifically designed to effectively eliminate chlorine, fluoride, pesticides, herbicides, unpleasant tastes, odors, and various volatile organic compounds (VOCs) from your tap water supply. It ensures that the water used for your saltwater aquarium is clean and free from harmful impurities.

Crafted from high-purity coconut shell activated carbon, this block filter boasts a remarkable ability to remove 99% of chlorine, taste, and odor from the water. It features food-grade, non-shedding polypropylene fabric to capture carbon fines, impurities, and sludge, while a silicone O-ring prevents bypass for maximum filtration efficiency. With a capacity to process up to 10,000 gallons of water at 2ppm chlorine, it offers long-lasting performance under a maximum water temperature of 140F and pressure of 120PSI.

This filter is an indispensable component for any serious reef aquarist seeking to maintain pristine water quality for their delicate marine inhabitants. By providing exceptionally pure water, it helps prevent the introduction of contaminants that can harm corals and fish, ensuring a healthier and more stable aquarium environment. It is compatible with systems like the AquaFX Blue Marlin and others, requiring replacement every 4-6 months to maintain optimal performance.
