Rite-Size "E" (Emperor 280/400)
The preassembled Emperor Cartridge filters water through a huge, 44-square inch pad. Made of double thick polyfiber, it traps more waste and dirt particles. Inside, each disposable cartridge contains two full ounces of Black Diamond Premium Activated Carbon...the best there is. It works longer and faster to adsorb harmful polllutants which discolor aquarium water and cause odors. The patented ribbed back that evenly distributes carbon for maximum water to carbon contact... no bypass, no "tea bag" effect. For best results, change monthly. Custom designed for the Emperor 280 Filter System and the Emperor Filter System.
