MARINELAND Penguin Power Filter Cartridge, Rite-Size C

Like all Marineland filters, the Marineland Rite-Size C Cartridge is designed to meet the highest standards of water purification and operational ease. These are pre-assembled mechanical and chemical filters that filter water through a pad of double-thick poly fiber and then thoroughly clean it using Marineland’s patented Black Diamond Premium Activated Carbon. The result is crystal-clear water free of waste, debris, and muckiness so you can better view your fish.
