Marineland Millennium 2000 and 3000 Filter Cartridge, Rite-Size M, 4-pack
At Marineland, we design our filter cartridges to meet the absolute highest standards of water purification, performance, and operational ease. Each pre-assembled cartridge slides 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 poly-fiber. 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 even distribution of activated carbon to deliver maximum water-to-carbon contact. The result? Crystal clear, crystal clean water. Rite-Size M fits Millennium 2000 and Millennium 3000.
