Marineland, they design their 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 the even distribution of activated
carbon to deliver maximum water-to-carbon contact. The result? Crystal clear, crystal
There's a Rite-Size Cartridge for every Penguin Filter, Emperor Filter, and Millennium
Power Filter. Plus, the custom Eclipse Filter Cartridge is designed specifically for
horizontal placement in our extensive selection of Eclipse systems. Our color-coded
packaging ensures fool-proof cartridge selection.
amazing what these take out of water by aj10/05/2011
I am always grossed out at how dirty these filters get in less that 1 week. I have 2 big goldfish and two catfish and the filter is plugged in short time( I do NOT overfeed) and I change water every 2.5 wks. These definetly clean well.
