Keep water crystal clear and promote growth of corals in saltwater aquariums as well as plants in freshwater aquariums with the ultimate filtration and convenience of API Bio-Chem Zorb Crystal Filter Cartridge. Unique blend of pharmaceutical-grade ion exchange resins, research-grade organic scavenger resins and high porosity activated carbon, this filter removes organic materials including colors, odors, heavy metals, toxic gases and compounds that carbon, alone, can't remove. It also eliminates light-blocking impurities to help stimulate coral and plant growth.
