Marineland B Rite Size Filter Cartridge PF125 for Penguin Filters. Marineland filter cartridges are designed to meet the absolute highest standards of water purification performance and operational ease.
Each preassembled 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 polyfiber. Debris and waste particles are trapped, and water is chemically filtered through Marineland's Black Diamond Premium Activated Carbon.
For use with Penguin 125 and Penguin 150
