The preassembled Emperor Cartridge
filters water through a 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 Activated Carbon. It works longer and faster to
absorb harmful pollutants which discolor aquarium water and cause odors. It's
better than a bag! Just shake and rinse. The patented ribbed back design evenly
distributes carbon for maximum water-to-carbon contact. No "tea bag"
effect...just crystal clear, crystal clean water. Does mechanical and chemical
filtration.
