The Emperor Filter Cartridges are pre-assembled and filter water through a 44-square inch pad. Made of double thick polyfiber, it traps more waste and dirt particles than conventional filter cartridges. Each disposable cartridge contains two full ounces of Black Diamond Activated Carbon. It works longer and faster to absorb harmful pollutants which discolor aquarium water and cause unwanted odors. It's better than a separate bag. The patented ribbed back design evenly distributes carbon for maximum water-to-carbon contact. No "tea bag" effect...just crystal clear, crystal clean water. Performs mechanical and chemical filtration.
Rite-Size Cartridges E - Fits all Emperor Bio-Wheel Filtrations Systems.
