The Marinelandbrand designs the 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 Black DiamondPremium 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.
