These preassembled Eclipse Replacement Cartridges slide easily into place, providing superior mechanical and chemical filtration, and making replacement fast, dry and effortless. The cartridge mechanically filters water through a pad of double thick polyfiber. Debris and waste particles are trapped, and water is chemically filtered through Marineland's Black Diamond Premium Activated Carbon. Inside the cartridge, a patented ribbed backing ensures the even distribution of activated carbon to deliver maximum water-to-carbon contact.
