Marineland Rite-Size Cartridges are designed to meet the 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. Cartridges mechanically filter water through a pad of double thick poly-fiber. Debris and waste particles are trapped, and water is then chemically filtered using Marineland Black Diamond Premium Activated Carbon. The result - super-clean, crystal clear water!
These Rite-Size C Filter Cartridges are compatible with the Marineland Penguin 170B, 200B, 330B, 350B, and the Aqua-Tech 20-40 and 30-60.
